Quality Control

Our 2,3-Bis-Sulfanylpropane-1-Sulfonic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing specifications such as assay (by HPLC or titration), impurity profiles, and physical characteristics. Our quality commitment supports applications requiring high-purity intermediates, including pharmaceutical development.

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 (moisture-sensitive) nature and tendency to be easily oxidized, it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize headspace in opened containers.
