Gold(III) chloride, traditionally called auric chloride, is an inorganic compound of gold and chlorine with the molecular formula Au₂Cl₆. The "III" in the name indicates that the gold has an oxidation state of +3, typical for many gold compounds. It has two forms, the monohydrate (AuCl₃·H₂O) and the anhydrous form, which are both hygroscopic and light-sensitive solids. This compound is a dimer of AuCl₃. This compound has a few uses, such as an oxidizing agent and for catalyzing various organic reactions.
