Silver oxide for portuguese laboratories
Silver(I) oxide is a dark brown-black, light-sensitive powder used as a mild oxidant and base in organic synthesis: Koenigs–Knorr glycosylation, O-alkylation of sensitive substrates, oxidation of aldehydes to carboxylic acids, and the preparation of silver carboxylates and silver N-heterocyclic carbene (NHC) transfer agents. It is the cathode material of silver-oxide button cells, a precursor for silver catalysts and conductive silver films, and a yellow colourant for glass and ceramic glazes. Decomposes cleanly to silver and oxygen above about 280 °C. Each lot is assayed for silver and released with a certificate of analysis. Full documentation — GHS classification, safety data sheet, certificate of analysis by lot — is on the Silver oxide product page.
Used for Organic synthesis, Batteries, Catalysis and Glass & ceramics. As a dangerous good it ships to Portugal by the licensed courier; the surcharge is one per consignment, not per pack.

Questions and answers
How quickly can Silver oxide be delivered to Portugal?
3 to 4 working days after dispatch from Dublin by licensed ADR/IATA dangerous-goods courier, which can take a day longer than the standard service. Making or packing your lot is usually same week; the lead time is stated on the quotation. Dangerous-goods items ship with UN-specification packaging.

Portuguese businesses that supply a valid PT VAT number, checked live against the EU VIES register, are invoiced with the reverse charge at 0% VAT (intra-community supply, Article 138 of the VAT Directive). Without a valid VAT number, Irish VAT at 23% is added.
How much does Silver oxide cost in Portugal?
Every order is quoted individually in EUR excluding VAT: the price follows the silver spot price at the time of quoting and the pack sizes you choose. The quotation is numbered, holds the metal price for 7 days, and states shipping to Portugal and any dangerous-goods surcharge.

What is Silver oxide called in Spanish?
Óxido de plata(I) (Spanish). The English name and the CAS number 20667-12-3 identify it unambiguously on the quotation and the certificate of analysis.
