Quality Control

Our Benzoyl Chloride, 4-Ethenyl- (9Ci) is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by GC or HPLC and identity confirmation (IR, NMR), to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications. We support cGMP-compliant production for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C (refrigerated) or as specified on the label. This material is hygroscopic (moisture-sensitive) and highly volatile. Keep away from heat, sparks, open flames, and strong bases. Use under an inert atmosphere (e.g., nitrogen or argon) for prolonged storage to maintain stability.
