Cobalt chloride hexahydrate

Cobalt chloride hexahydrate (CAS 7791-13-1), also known as cobalt (II) chloride hexahydrate, is an inorganic cobalt salt supplied as a distinctive pink-to-red crystalline solid. It functions across industrial chemistry as a catalyst precursor, colorant, and surface treatment agent, with demand driven by its reactivity and solubility in aqueous and polar systems.

In electroplating and surface finishing, it is used to deposit cobalt-containing layers that improve hardness and corrosion resistance on metal substrates for various industrial applications. Textile and leather processors apply it as a dye mordant, fixing colorants to fiber and improving wash fastness in finished goods to ensure long-lasting color quality and durability.

Agricultural formulations incorporate it as a cobalt micronutrient source in fertilizers and animal feed supplements where cobalt deficiency must be corrected for optimal livestock health. In catalyst manufacturing, it serves as a precursor for hydrodesulfurization and Fischer-Tropsch catalysts, where controlled cobalt loading on support materials is critical to performance.

Cobalt chloride hexahydrate is supplied as pink crystalline powder or granules. Standard commercial grades include technical, reagent, and laboratory-grade material for diverse uses. Purity levels typically range from 97% to 99%+. Packaging ranges from small drums to bulk quantities depending on specific application requirements and logistical needs of the client.
