Sodium thiosulfate pentahydrate

Sodium thiosulfate pentahydrate (CAS 10102-17-7 ), also known commercially as antichlor, is an inorganic salt used across industrial and pharmaceutical supply chains as a reducing and dechlorination agent. It neutralizes excess oxidants in solution, making it a go-to input wherever chlorine or heavy metal control is required. In water treatment, it dechlorinates municipal and process water prior to discharge. This chemical helps facilities meet regulatory limits without the need for complex equipment. Pharmaceutical manufacturers use it as an antidote formulation ingredient and as a stabilizer in injectable preparations. It is essential where oxidative degradation must be controlled. Textile and paper producers apply it to neutralize residual chlorine after bleaching, preventing fiber or pulp damage that would compromise quality. In food processing, it functions as an antioxidant and dough conditioner, supplied to specification for direct food contact applications. The material is supplied as white crystalline granules or powder. Standard commercial grades include food-grade ( FCC ), USP , and technical grade, with purity levels typically at 99% or higher. These standards ensure reliability across diverse manufacturing sectors. Packaging ranges from small drums to bulk supersacks, supporting both formulation-scale and industrial-volume procurement. This flexibility allows for efficient logistics and storage in various facility types. Contact us for supply of Sodium thiosulfate pentahydrate Request Quote
