Sodium Thiosulphate, offered by Veeransh Chemicals, is a high-purity, crystalline compound valued for its reducing, dechlorinating, and photographic fixing properties. It is widely used in water treatment, photography, textile processing, gold extraction, and chemical synthesis due to its excellent solubility and chemical stability. In water treatment, it neutralizes chlorine and cyanide compounds, while in photography, it serves as a reliable fixer for silver halide removal. With assured purity, consistent performance, and global export quality, Veeransh Chemicals provides Sodium Thiosulphate that meets the stringent requirements of both industrial and laboratory applications.
Sodium Thiosulphate (Na₂S₂O₃, CAS 7772-98-7) is a versatile crystalline salt known for its strong reducing and complexing properties. It is used in water treatment (dechlorination), photographic fixing (silver halide removal), gold extraction, textile bleaching, analytical chemistry (iodometric titration), and as a pharmaceutical antidote for cyanide poisoning. Its high solubility, controlled impurity profile, and stability under normal conditions make it indispensable across industrial, laboratory, and healthcare sectors.
