Description
- General description: Sodium tetrathionate dihydrate is the dihydrate of sodium tetrathionate. It has been synthesized from sodium thiosulfate by iodine oxidation.[1] Its crystals exhibit monoclinic crystal system and space group C23-C2.[2]
- Application: Sodium tetrathionate dihydrate may be used to compose the 0.2M Tris buffer in a study.[3]
- Other Notes: Thiosulfating agent; it reacts with thiols, e.g. cysteine to S-sulfo-thiols, used in the quantitative determination of total cysteine/cystine in proteins[4]; Reversible inactivation of enzymes[5]
