Quality Control

Our Benzoic Acid, 3,4-Diamino-2-Methoxy-, Methyl Ester is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided with each shipment, detailing all relevant specifications. We can support compliance with various pharmacopeial or customer-specific standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flames.
