Quality Control

Our 3,3',5'-Tricarboxylic Biphenyl is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting all specifications are provided with each shipment to guarantee traceability and consistency.

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 purity and handling properties. Keep away from incompatible materials such as strong bases and oxidizing agents.
