Description

Silver sulfate (CAS 10294-26-5 ) is an inorganic silver salt used across water treatment, pharmaceutical, and specialty chemical applications. Its controlled release of silver ions underpins its function as a biocidal agent and analytical reagent. In water treatment, this compound acts as a catalyst and masking agent during COD testing, where it suppresses chloride interference in standard analytical procedures. This ensures accurate measurements in environmental monitoring. Pharmaceutical and healthcare formulators use it as an antimicrobial active in wound care preparations and topical treatments targeting bacterial contamination. It provides a reliable source of silver ions for medical applications. Personal care manufacturers incorporate it into preservation systems where sustained silver ion release is required to maintain product integrity. This helps prevent microbial growth in various consumer formulations. It also serves as a precursor in the synthesis of other silver compounds and as a reference standard in laboratory and quality control workflows. Its versatility makes it a staple in chemical synthesis. The product is supplied as a white to off-white crystalline powder. It is available in reagent-grade and ACS -grade specifications, supporting both laboratory and industrial procurement requirements. Packaging is typically offered in small quantities for analytical use through to bulk quantities for industrial-scale water treatment operations. This flexibility allows for efficient supply chain management. Contact us for supply of Silver sulfate Request Quote
