Cupric sulfate monohydrate

Cupric sulfate monohydrate (CAS 10257-54-2) is a copper-based inorganic salt in a lower-hydration form than the common pentahydrate. Also known in regulatory contexts as Copper sulfate, monohydrate.

Where is Cupric sulfate monohydrate used?

• Water treatment: controls algae and microbial growth in reservoirs, cooling towers and municipal systems
• Mining and hydrometallurgy: leaching circuits and electroplating baths to manage copper ion concentration
• Textile and leather processing: mordant and preservative in dyeing and tanning
• Agriculture: copper source in animal feed supplements and active ingredient in fungicidal formulations
• It also functions as a biocide, coagulant and micronutrient source.

Good to know: Higher copper content by weight than the pentahydrate, useful where precise copper dosing is required to maintain water quality standards. Consistent metal content per batch affects color fastness and durability.

Commercial specifications

• Higher copper content by weight for dose-sensitive applications
• Powder or granule; particle size influences dissolution rate
• Bulk supply standard; smaller packaging for specialized formulators
