Quality Control

Our 2-(3-Aminophenyl)Acetic Acid Ethyl Ester 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 specifications is provided with each shipment. We support compliance with global regulatory frameworks, including REACH.

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 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.
