Quality Control

Our 5-Mercapto-1H-Tetrazole-1-Methanesulfonic Acid Disodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) detailing specific results for assay, related substances, and other critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under dry conditions. For long-term storage, consider using an inert atmosphere to minimize oxidation.
