Product Description:

Potassium tetrathionate (K₂S₄O₆, CAS 13932-13-3) is an inorganic salt composed of potassium cations and the linear tetrathionate anion (S₄O₆²⁻). It typically appears as a white to off-white crystalline powder. It is a member of the polythionate series of compounds. Its primary application is in analytical chemistry as a reagent for the iodometric titration of sulfite and thiosulfate. It serves as a stable and convenient source of tetrathionate ion in solution for specific redox reactions. It is also used in biochemical research, particularly in the study of sulfur metabolism in microorganisms and plants, where it can act as an intermediate or substrate. As a chemical reagent, it is handled as a stable solid but should be stored in a cool, dry place away from strong oxidizing or reducing agents. It is not typically considered a high-volume industrial commodity but is a specialized reagent for laboratory use.
