Quality Control

Every batch of 3-Amino[1,1'-Biphenyl]-4,4'-Dicarboxylic Acid is produced and tested under a strict quality management system. We ensure high purity and batch-to-batch consistency through advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
