About Sodium Thiosulfate Pentahydrate

Sodium Thiosulfate Pentahydrate (CAS 10102-17-7) is a white, crystalline, efflorescent substance that is highly soluble in water. In the Indian market, it is primarily valued for its strong reducing properties, making it an indispensable chemical for neutralizing chlorine in municipal and industrial water treatment systems.

Beyond water treatment, the Indian textile industry relies heavily on this compound as an 'antichlor' to remove residual chlorine after bleaching processes, ensuring fabric integrity and preventing dye degradation. It also finds significant use in the pharmaceutical sector as a stabilizer and in laboratory environments as a primary standard for iodometric titrations.

When procuring in India, buyers should prioritize suppliers who provide COA (Certificate of Analysis) documentation confirming low heavy metal content, especially for pharma or food-grade applications. Given its tendency to effloresce, proper moisture-proof packaging is critical for maintaining product shelf life during transit across different climatic zones in India.
