Quality Control

Our 3-Chlorobenzal Bromide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all test results is provided with each shipment. We adhere to cGMP principles where applicable to support our customers' regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and light-sensitive nature, the container must be kept tightly sealed in a dry environment and opened under inert atmosphere for prolonged handling to minimize moisture uptake and decomposition.
