Zinc sulfate

Zinc sulfate (CAS 7733-02-0) is an inorganic zinc salt supplying bioavailable zinc across agricultural, industrial, and pharmaceutical supply chains. It functions as a micronutrient source, process chemical, and preservation agent depending on the application sector. In agriculture, it corrects zinc deficiency in crops and is incorporated into fertilizer blends and animal feed premixes to support livestock nutrition. Water treatment facilities use it as a coagulation aid and algaecide in municipal and industrial systems.

Textile and leather processors apply it during dyeing and tanning operations to fix colorants and control microbial growth in process baths. Pharmaceutical and personal care manufacturers use it as an active ingredient in ophthalmic solutions and astringent formulations. The compound is also utilized in anti-dandruff products and various topical applications. Zinc sulfate is supplied as a white crystalline powder or granules, with the monohydrate and heptahydrate forms being the most commercially traded.

Recognized grades include USP, BP, Ph. Eur., and FCC, covering pharmaceutical, food additive, and industrial procurement requirements. These standards ensure the material meets specific purity levels for sensitive manufacturing processes. Technical grade options are also available for large-scale industrial use. Bulk quantities are standard for agricultural and industrial buyers, with smaller packaged formats available for specialized feed and pharma applications.
