Quality Control

Every batch of our Butanedioic Acid, Chloromethyl Phenylmethyl Ester is manufactured and tested under a cGMP-compliant quality management system to ensure exceptional purity and batch-to-batch consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

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 after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
