Quality Control

Our 3-Aminophthalic Acid Hydrochloride Hydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after use to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
