Quality Control

Our production of Benzoyl Chloride, 5-Ethyl-2-Methoxy- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets exacting specifications for research and industrial use. Certificates of Analysis (COA) documenting all critical quality attributes are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature and classification as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as bases, amines, and oxidizing agents.
