Quality Control

Our 2,2'-Dithiobis[5-Methylbenzenesulfonic Acid] is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing key parameters such as assay, impurity profile, and physical characteristics is provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents, strong bases, and incompatible materials. Due to the presence of sulfonic acid groups and a disulfide bond, the material may be hygroscopic; protect from excessive moisture.
