Description

Copper acetate (CAS 142-71-2 ), also known as copper diacetate, is a copper salt of acetic acid used across chemical synthesis, agriculture, and specialty manufacturing. It functions primarily as a catalyst, biocide, and pigment precursor in industrial and formulation contexts. In organic synthesis, it serves as a catalyst for coupling reactions and oxidation processes. Agricultural formulations use it as a fungicide and algaecide active ingredient, particularly in treatments targeting mold, algae, and microbial growth on surfaces or in water systems. Personal care and cosmetic formulators incorporate it into products where controlled copper ion activity supports preservation or color effects in various specialized applications. In mining and metal processing, it acts as a reagent in electroplating baths and surface treatment processes to deposit or condition copper layers for industrial components. The material is supplied as a blue-green crystalline powder or monohydrate crystals. Technical grade is the standard commercial form, with purity levels typically ranging from 98% upward. Reagent and pharmaceutical-grade material is available for synthesis and controlled manufacturing applications where tighter specification is required for high-purity production environments.
