Copper Hydroxide (CAS 20427-59-2) is an inorganic copper salt supplied as a fine blue powder that releases copper ions slowly, and it is used as an agricultural fungicide for fruit and vegetable crops and as a precursor for cupric salts, catalysts, pigments and electronic ceramic formulations. It acts as a source of slow-release copper ions in agrochemical and industrial processes.
