CAS NO.: 7772-98-7

HS Code:28323000

Sodium thiosulphate anhydrous is a white crystalline salt with the chemical formula Na2S2O3. It is commonly used as a fixing agent in photography to remove any unexposed silver halide from the photographic film or paper. It is also used in various industrial processes, such as in the production of paper and textiles. Sodium thiosulphate anhydrous is typically produced by heating hydrated sodium thiosulphate, which then loses its water molecules, leaving behind the anhydrous form.
