Quality Control

Our 1,2,3-Benzothiadiazole-5-Carbonyl Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC and NMR, to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment to support your quality assurance and regulatory needs.

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 an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong acids and organic solvents.
