Quality Control

Our 4-Bromo-2-Chlorocinnamic Acid is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the stringent requirements of our global clientele. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment and is available upon request.

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 nature, the container must be kept sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
