Quality Control

Our production of Ethanesulfonic Acid, 2-((2,3-Dimercaptopropyl)Thio)-, Sodium Salt adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, impurities, and other critical parameters are provided and available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) after opening to maintain stability and prevent degradation.
