CAS RN | 10102-17-7 | EMPROVE Sodium Thiosulfate, Pentahydrate Crystals, USP, BP, Ph Eur

Also known as Sodium Hyposulfite Pentahydrate, this inorganic salt takes the form of transparent monoclinic crystals or granules. Incompatible with sodium nitrate, acids, strong oxidizing agents, iodides, silver salts, and mercury salts, it can also be irritating to eyes, respiratory system and skin. Odorless and colorless, this product should be stored desiccated at room temperature (15-30 °C).
