Copper sulfate monohydrate

Copper sulfate monohydrate (CAS 10257-54-2, EC 600-326-9) is an inorganic copper salt containing one molecule of water of crystallisation, commercially available under names including Cupric Sulfate Monohydrate and Copper(II) sulfate 1-hydrate. It carries no E-code designation and is distinct from the pentahydrate form commonly referenced in agricultural contexts.

In agriculture and water treatment, copper sulfate monohydrate functions as a biocide and algaecide by releasing cupric ions that disrupt enzyme activity in microbial and algal cells, inhibiting growth at controlled dosage rates. In mining and metals processing, it acts as a selective flotation activator, conditioning sulfide mineral surfaces to improve separation efficiency.

The material is supplied in technical and agricultural grades, with procurement subject to REACH registration requirements within the EU. Standard packaging formats include multi-wall bags and bulk quantities suited to industrial volumes. Buyers should confirm grade specification against intended application prior to ordering.
