Quality Control

Every batch of 3-Amino-2-(4-Methylphenylamino)Benzoic Acid is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency meet the high standards required for fine chemical intermediates. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

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 to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials.
