Quality Control

Our production of Benzoyl Chloride, 4,5-Dimethoxy-2-Methyl- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability for critical synthesis. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
