Quality Control

Our 2,1,3-Benzothiadiazole-4-Carbonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep the container tightly sealed in a dry environment to prevent hydrolysis and degradation.
