Quality Control

Every batch of 3,5-Diamino-4-Methyl-Benzoic Acid Ethyl Ester is produced and tested under a strict quality management system. We guarantee high purity and consistency to meet the exacting standards of our global B2B clients. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to ensure full traceability and compliance with your internal specifications.

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 and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
