Quality Control

Our Benzoic Acid, 4-Amino-3-Hydroxy-2-Nitro- (9Ci) is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay and impurity profiles. We adhere to cGMP principles where applicable to support our customers' regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Recommended storage temperature is 2-8°C for long-term stability.
