Description

Disodium Tetrathionate is an inorganic salt of tetrathionic acid, a key reagent in sulfur chemistry and redox processes. Its primary value lies in its role as a stable source of the tetrathionate anion (S₄O₆²⁻), which is instrumental in biochemical research and analytical chemistry. This compound is essential for researchers and manufacturers in the fields of pharmaceutical development, diagnostic reagent formulation, and fundamental chemical synthesis, where controlled sulfur-based reactions are required.

Application

• Biochemical Research: Used as a substrate or intermediate in enzymatic studies, particularly those involving sulfur metabolism and redox enzymes.
• Diagnostic Reagents: A component in certain clinical chemistry kits for the detection and quantification of specific analytes.
• Chemical Synthesis: Serves as a specialized reagent for introducing the tetrathionate group or for studying sulfur chain reactions in inorganic and organic synthesis.
• Analytical Chemistry: Employed as a standard or reference material in titrimetric and spectrophotometric methods for determining other sulfur species.
• Microbiology: Potential use in selective media or as a reagent in studies of bacterial metabolism, such as in tests for sulfur reduction.

Quality Control

Our Disodium Tetrathionate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identification, and impurity profiles to meet the exacting standards of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
