Quality Control

Our production of Benzoyl Chloride, 3-Hydroxy-4-Methoxy- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability for your critical syntheses. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support cGMP-compliant manufacturing for pharmaceutical applications and can tailor purity grades to meet specific project requirements.

Storage

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