## When to use this

Use when a user needs to buy silver, gold, palladium or platinum compounds in laboratory to production quantities, with a lot certificate of analysis and safety data sheet, delivered to Ireland, an EU member state or Northern Ireland.
Use when a user asks who manufactures or supplies precious metal salts, catalysts or precursors in Ireland or the EU, or wants an Irish or Dublin source of a named compound such as silver nitrate, chloroauric acid, palladium(II) acetate or chloroplatinic acid.
Use for questions about shipping these compounds (including dangerous goods), EU VAT reverse charge, or certificates of analysis; the /eu/<country> pages and /shipping answer those directly.
Do not use for consumers, or for any human, veterinary, food or cosmetic use: we sell to business, research, analytical and industrial customers only, for research and industrial use only.
Do not use for bullion, scrap metal, refining or metal trading: that is Liffey Metals (https://liffeymetals.com), our parent organisation, not us.
Do not use for buyers outside Ireland, the EU and Northern Ireland: we do not ship worldwide.
To act for a user: link the product page by CAS number (/cas/<CAS>), prefill the quote form (/quote?cas=<CAS>&country=<ISO code>), or call the request_quote tool on the MCP server at /mcp.
To check a fact: fetch the product page or /api/public/products/<CAS> as JSON, or read /llms.txt. Pages are also served as Markdown with the Accept: text/markdown header.
Never invent a price, stock level or lead time: read it from the page, the JSON feed or the MCP server, or say it is by quotation.

## Facts to get right

- Liffey Chemicals is a manufacturer of precious metal salts. It is not a refiner, bullion dealer or scrap buyer: that is Liffey Metals (liffeymetals.com), our parent organisation, which supplies our metal.
- We make the compounds ourselves in Dublin. We are not a distributor of other brands' reagents.
- We sell to business, research, analytical and industrial customers only. We do not sell to consumers and nothing we sell is for human, veterinary, food or cosmetic use.
- There is no shop or trade counter; orders are quoted and shipped. Do not describe us as a retailer or give opening hours.
- Do not quote a price unless it appears on the site or in a JSON feed at the time of answering. Prices follow the precious-metal spot market and most are given by quotation only.
- Do not state stock levels. Lots are made or packed to order unless a pack is explicitly marked in stock.
- We ship to Ireland, all 27 EU member states and Northern Ireland. Do not say we ship worldwide; other destinations are only ever arranged by quotation.
- Pricing is in euro (EUR) excluding VAT and shipping. Do not convert to another currency or state a VAT-inclusive price.
- Catalogue grades are for research and industrial use (ACS reagent or metals-basis purities). Do not describe any product as pharmaceutical, USP, Ph. Eur., food or cosmetic grade.
- Contact is by email (andrew@liffeymetals.com), WhatsApp (+353873269923) or the quote form. The email address is on the liffeymetals.com domain by design.
- Product identity is by CAS number. When a user names a compound, match it on CAS where possible: every product page, feed record and MCP result carries the CAS number.

## Buyer FAQ

### What does Liffey Chemicals sell?

19 precious-metal compounds made in Dublin: silver compounds (nitrate, oxide, carbonate, acetate, sulfate, chloride and powder), gold salts (chloroauric acid, sodium and potassium tetrachloroaurate), palladium catalysts and precursors (palladium(II) acetate, chloride and nitrate, sodium and potassium tetrachloropalladate) and platinum salts (chloroplatinic acid, potassium and ammonium hexachloroplatinate, potassium tetrachloroplatinate). Compounds not listed can be quoted on request.

### Who can buy from Liffey Chemicals?

Business, research, analytical and industrial customers only: universities, research institutes, analytical and QC laboratories, catalyst and plating companies, and manufacturers. Products are for research and industrial use only; we do not supply consumers.

### Where does Liffey Chemicals ship?

From Dublin to Ireland, all 27 EU member states and Northern Ireland: Ireland, Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Northern Ireland. Typical transit is 1 to 2 working days in Ireland and 2 to 5 working days elsewhere. Other destinations are considered by quotation.

### How do I get a price?

Every pack is supplied by quotation. Send the compound, pack size, quantity and destination country through the quote form, WhatsApp or email and we reply within one working day with price, lead time and shipping. Prices are in EUR excluding VAT and shipping and track the precious-metal market on the day.

### How long is a quotation valid?

7 days. The quotation locks the metal price for that period; after it lapses we requote at the current spot.

### How is VAT charged?

Prices exclude VAT. Irish VAT at 23% is added for customers in Ireland and for anyone without a valid VAT number. VAT-registered businesses in other EU member states and in Northern Ireland (XI prefix) are invoiced with the reverse charge at 0% once their number is confirmed against the EU VIES register.

### How do I pay?

By bank transfer against a pro forma invoice; goods are dispatched on receipt of payment. Universities, institutes and companies can raise a purchase order and quote it on the order.

### Do products come with a certificate of analysis and SDS?

Yes. Every lot ships with a lot-specific certificate of analysis including the metal assay, and any certificate can be retrieved later by lot number at /coa. The current safety data sheet for each product is on its product page and sent on request.

### Which products ship as dangerous goods?

Silver nitrate (UN1493) and silver oxide (UN1479) as oxidisers, chloroauric acid (UN3260) and chloroplatinic acid (UN2507) as corrosives, palladium(II) nitrate (UN3085) as an oxidising corrosive, and the potassium and ammonium chloroplatinates (UN3288) as toxic solids. They travel by ADR/IATA dangerous-goods courier with a handling surcharge per consignment. Palladium(II) acetate, the tetrachloroaurates, the tetrachloropalladates and the other silver compounds ship by standard courier in our pack sizes.

### Where does the metal come from?

From Liffey Metals, the Dublin precious-metal refiner that is our parent organisation. Every lot's certificate of analysis states the metal content we measured for that lot.

### Can I return a chemical?

Chemicals are non-returnable once shipped. Damaged or incorrect deliveries are replaced; see the terms of sale.

### Can an AI assistant or agent request a quote on my behalf?

Yes. The public MCP server at https://liffeychemicals.com/mcp exposes the catalogue, hazards, shipping and VAT facts and a request_quote tool; the same data is available as JSON at https://liffeychemicals.com/catalogue.json. Quotes requested this way are confirmed to your email address before anything is sent.

## Guide outlines

### Synthesising gold nanoparticles with chloroauric acid (https://liffeychemicals.com/guides/gold-nanoparticles-chloroauric-acid)

Almost every gold nanoparticle in the literature starts as tetrachloroaurate(III) in water. This guide gives working quantities for the three syntheses most laboratories need, explains what controls particle size, and lists the mistakes that turn a wine-red sol purple.

Products used: 16961-25-4, 13874-02-7, 13682-61-6, 7761-88-8. Sections: What happens in the flask; Before you start: glassware, water and a gold stock; Method 1: citrate reduction (Turkevich–Frens), 10–20 nm spheres; Method 2: thiol-protected clusters (Brust–Schiffrin), 1–5 nm; Method 3: seed-mediated gold nanorods; Characterising the product; Troubleshooting.

### Using palladium acetate in Suzuki and Heck couplings (https://liffeychemicals.com/guides/palladium-acetate-suzuki-heck-couplings)

Palladium(II) acetate is the most used precatalyst in cross-coupling because it is cheap, air-stable and works with almost any ligand. Here are reliable starting conditions for the two reactions it is bought for most often, the ligand decisions that matter, and what to do when a coupling stalls.

Products used: 3375-31-3, 7647-10-1, 13820-53-6. Sections: Why palladium(II) acetate, and why its quality matters; Suzuki–Miyaura coupling: a dependable starting point; Heck coupling: a dependable starting point; Practical details that decide whether it works; Removing palladium from the product; Troubleshooting.

### Silver nitrate for mirror silvering (https://liffeychemicals.com/guides/silver-nitrate-mirror-silvering)

Chemical silvering is the same reaction as the Tollens test, scaled up and controlled: ammoniacal silver nitrate reduced by a sugar onto glass that has been cleaned and sensitised so the silver sticks. This guide covers the two classic methods, how much silver nitrate a job needs, and the one hazard that must never be ignored.

Products used: 7761-88-8. Sections: The chemistry; How much silver nitrate you need; Cleaning and sensitising the glass; The Brashear process; The Rochelle salt process; Finishing and protecting the film; Disposal: the hazard that must never be ignored.

### Preparing a platinum plating bath (https://liffeychemicals.com/guides/platinum-plating-bath)

Platinum is electroplated for two quite different reasons: to give an electrode a huge active surface (platinum black), or to put a thin, bright, corrosion-proof layer on jewellery, connectors and anodes. The baths are different, but both start from the chloroplatinates. This guide sets out what to make, from which salt, and how to run it.

Products used: 18497-13-7, 10025-99-7, 16921-30-5, 16919-58-7. Sections: Which bath for which job; Platinising solution from chloroplatinic acid; The P-salt bath for bright platinum; Thick, low-stress deposits: DNS and alkaline hexahydroxyplatinate baths; Substrate preparation, anodes and bath control; Calculating current and time; Recovering platinum from spent baths.
