Description

Cupric sulfate monohydrate (CAS 10257-54-2 ) is a copper-based inorganic salt supplied in a lower-hydration form than the common pentahydrate. It offers higher copper content by weight for dose-sensitive applications. Known in regulatory contexts as Copper sulfate, monohydrate, it functions as a biocide, coagulant, and micronutrient source. It is used extensively across industrial and agricultural supply chains for various chemical processes. In water treatment, it controls algae and microbial growth in reservoirs, cooling towers, and municipal systems. This is particularly useful where precise copper dosing is required to maintain water quality standards. Mining and hydrometallurgical operations use it in leaching circuits and electroplating baths to manage copper ion concentration. It ensures stability and efficiency in metal recovery and surface finishing applications. Textile and leather processors apply it as a mordant and preservative in dyeing and tanning processes. Consistent metal content per batch directly affects color fastness and the overall durability of the material. In agriculture, it serves as a copper source in animal feed supplements and as an active ingredient in fungicidal formulations. It is also used in algaecidal products to protect crops and livestock health. Cupric sulfate monohydrate is available as a powder or granule, with particle size influencing dissolution rate. Technical and agricultural grades are the most commonly sourced for large-scale industrial operations. Specifications are aligned to EPA pesticide registration requirements and feed-grade standards where applicable. Bulk supply is standard for industrial buyers, with smaller packaging available for specialized formulators. Contact us for supply of Cupric sulfate monohydrate Request Quote
