Quality Control

Our 2-Chloro-4-Fluoro-5-Methylbenzenesulfonamide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and stringent control of residual solvents and impurities. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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 tightly sealed after each use to prevent degradation from atmospheric moisture.
