Quality Control

Our 3,3"-Dihydroxy-[1,1':4',1"-Terphenyl]-4,4"-dicarboxylic acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis. Certificates of Analysis (COA) documenting all critical parameters are provided to ensure traceability and compliance with your research or production specifications.

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 sensitivity, the material should be stored under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from incompatible materials such as strong oxidizing agents.
