Copper oxychloride

Copper oxychloride (CAS 1332-40-7, EC 215-572-9) is an inorganic copper-based compound commercially available under trade names including CUPOX, COBOX, Oxicob, BLITOX, and COPTOX. It belongs to the salts and minerals category and carries the HS code 28274100.

In agriculture, copper oxychloride functions as a contact fungicide and bactericide, disrupting enzyme activity in fungal cell membranes to control downy mildew, blight, and bacterial canker on crops. In water treatment and pulp and paper processing, it acts as a biocidal preservative, inhibiting microbial growth through copper ion release.

Copper oxychloride is supplied as a technical-grade bluish-green powder and is subject to REACH registration requirements within the EU. Procurement quantities are available in standard industrial packaging formats. Buyers should confirm compliance with applicable biocidal product regulations under BPR (EU 528/2012) for their intended application.
