Quality Control

We supply 6,6',6",6'"-([1,1'-Biphenyl]-3,3',5,5'-Tetrayl)Tetrakis(2-Naphthoic Acid) in high-purity grades suitable for demanding research and development applications. Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with customer specifications. Standard analytical techniques including HPLC, NMR, and elemental analysis are employed. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Recommended storage temperature is 2-8°C for extended stability.
