Quality Control

Every batch of Benzoyl Chloride, 4-Formyl- (9Ci) is produced and tested under a strict quality management system to ensure batch-to-batch consistency and reliability for your critical syntheses. We provide comprehensive analytical data, including HPLC purity, identity confirmation (IR, NMR), and impurity profiling. A Certificate of Analysis (COA) detailing all specifications is available with each shipment and upon request.

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 hygroscopic and highly volatile nature, it is recommended to handle and store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Recommended storage temperature: 2-8°C.
