Quality Control

Our 4-[(4-Methoxyphenyl)Amino]-3-Nitrobenzoic Acid undergoes rigorous quality testing to ensure compliance with industry standards. We implement strict in-process controls and final product analysis to guarantee batch-to-batch consistency and high purity. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

Storage

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