Gold(I) trisodium disulphite (Cat No.: M078372) is an inorganic gold compound containing gold in the +1 oxidation state complexed with disulphite (or more precisely, sodium metabisulfite) ligands. It typically appears as a pale yellow solid and is water-soluble. This compound is used in photographic processing, gold plating, and as a mild reducing agent in chemical synthesis. Its coordination with sulfur-containing ligands makes it useful in studying gold-sulfur interactions, and it may also serve as a precursor for preparing other gold(I) complexes.
