Quality Control

Our 3-Amino-5-Phenylbenzoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We adhere to cGMP principles where applicable to guarantee supply consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
