Copper(II) chloride is used as a mordant in dyeing and printing of fabrics, as an ingredient of isomerization and cracking catalysts, and as a desulfurizing and deodorizing agent in petroleum industry. Other important applications are in copper plating of aluminum, preparation of copper standard solutions, test for molybdenum, in tinting-baths for iron and tin, in pigments for ceramics and glasses, as a fixer and desensitizer reagent in photography, in mercury extraction from ores, in laundry-marking and invisible inks, and in manufacture of several copper salts. Copper chloride dihydrate may be also used as catalyst to cleave tetrahydropyranyl (THP) ethers and t-butyldimethylsilyl (TBDMS) ethers and to chemoselectively hydrolyze semicarbazones to carbonyl compounds. Solution of copper (II) chloride is used for plating on aluminum and for tinting germanium and tin.
