Quality Control

Our Benzoyl Chloride, 4-Cyano-2-Ethoxy- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing including HPLC, GC, NMR, and IR spectroscopy to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support cGMP compliance for pharmaceutical applications and can tailor purity grades to meet specific project requirements, from research to commercial scale.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, amines, alcohols, and oxidizing agents. Due to its nature as a strong acid/organic solvent derivative, it should be handled in a fume hood. Recommended storage temperature is 2-8°C for long-term stability. Keep container tightly sealed when not in use to prevent moisture absorption and decomposition.
