Cupric chloride

Cupric chloride (CAS 7447-39-4), also known commercially as CuCl2, is an inorganic copper salt used across industrial chemistry as a catalyst, biocide, and metal surface treatment agent. Its reactivity with organic and inorganic substrates makes it a practical choice across multiple manufacturing sectors. In chemical synthesis and petrochemical processing, it functions as a catalyst or catalyst precursor.

It is frequently utilized in chlorination reactions and oxidative coupling processes. Textile and leather manufacturers use it as a mordant to fix dyes onto fiber substrates, improving color fastness in finished goods. Water treatment operations employ it as a biocidal agent to control algae and microbial growth in industrial water systems. In mining and hydrometallurgy, it serves in copper etching and metal recovery processes.

It is particularly useful in printed circuit board manufacturing where controlled copper dissolution is required. The material is supplied as an anhydrous powder or as the dihydrate form in crystalline or granular format. Standard commercial grades include technical grade and reagent grade, with anhydrous and dihydrate variants available depending on application requirements. Quality is maintained according to ACS standards.

Packaging typically ranges from small laboratory quantities to bulk industrial supply in fiber drums or supersacks. This ensures safe transport and storage for various industrial and laboratory environments.
