Description
Copper (CAS 7440-50-8, EC 231-159-6, formula Cu) is a naturally occurring reddish-brown metal sourced from ores including malachite, cuprite, and chalcopyrite. It is traded under abbreviations such as m3r, m3s, CuEP, and cum3, and carries HS code 74081900. No E-code designation applies.
In water treatment and agriculture, copper acts as a biocide by disrupting microbial cell membranes and enzyme function at low concentrations. In personal care formulations, copper peptides function as skin-conditioning agents that support collagen synthesis. As a catalyst, copper accelerates oxidation and coupling reactions in pharmaceutical and biotechnology manufacturing processes.
Copper wire is available in electrolytic grades including CuEP, compliant with REACH regulations and traceable to EN and ASTM standards. Pharmaceutical and cosmetic applications require documented purity specifications aligned with Ph.Eur. or USP monographs. Packaging formats vary by grade and volume; procurement teams should confirm specifications directly with our technical team.
