Platinum(II) chloride is the chemical compound PtCl2. It is an important precursor used in the preparation of other platinum compounds. It exists in two crystalline forms, but the main properties are somewhat similar: dark brown, insoluble in water, diamagnetic, and odorless
P 1943 (OTTO) Platinum(II) chloride (about 73% Pt) Cas no 10025-65-7 - used as a catalyst for a variety of C-C bond, C-O bond, and C-N bond formation reactions. It acts as a precursor to prepare other platinum compounds such as cisplatin and dichloro(cycloocta-1,5-diene)platinum(II).
