Chloroplatinic acid hexahydrate is the standard platinum precursor for platinum catalysts (Adams' catalyst PtO2, Pt/C, Speier's and Karstedt's hydrosilylation catalysts), electroplating and platinising of electrodes, platinum nanoparticles and fuel-cell electrocatalysts. Each lot is supplied with a platinum assay and full certificate of analysis.
High-purity silver nitrate for analytical, photographic, electrochemical and synthetic use. The standard precursor for silver nanoparticles, silver halide chemistry, Tollens' reagent, argentometric titration (Mohr, Volhard, Fajans) and electroplating baths. Supplied as free-flowing crystals with a lot-specific certificate of analysis including trace-metal assay.
Palladium(II) acetate is the most widely used palladium precatalyst in organic synthesis — Suzuki–Miyaura, Heck, Buchwald–Hartwig, Sonogashira and Stille couplings, C–H activation and Wacker-type oxidations. Also used to prepare Pd nanoparticles and supported palladium catalysts. Supplied as the pure trimer with lot-specific palladium assay.
