Quality Control

Our 2-Mercapto-5-Sulfonyl-Benzimidazole, Potassium Salt is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting all critical parameters are 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, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under dry conditions. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
