Quality Control

Our 4-Amino-3-Methylbenzoic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, and is supplied with a corresponding Certificate of Analysis (COA). We adhere to cGMP principles where applicable, ensuring the material meets the stringent requirements of pharmaceutical and fine chemical applications.

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.
