Quality Control

Our 2',2",2"',5',5",5"'-Hexamethyl-[1,1':4',1":4",1'":4'",1"-Quinquephenyl]-4,4"-Dicarboxylic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific research or cGMP guidelines upon request.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. Keep away from incompatible materials.
