Copper Sulphate Pentahydrate 99% Plating Grade

Copper Sulphate Pentahydrate 99% Plating Grade (CAS 7758-99-8, molecular formula CuSO4·5H2O) is a process chemical for electronics and metal finishing, where trace metal content and particle contamination matter as much as headline assay. China Chemicals supplies it at 99% min in pack sizes from 1 kg through to 500 kg Pallet, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Blue Vitriol, Bluestone, Cupric Sulphate. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Acid copper electroplating and PCB through-hole plating
Electroless copper and printed circuit metallisation
Flotation reagent in zinc and lead mineral processing
Algaecide in reservoirs and irrigation systems
Fungicide component in Bordeaux mixture
