Quality Control

Our 5'-Cyano-[1,1':3',1''-Terphenyl]-4,4''-Dicarboxylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using a desiccator.
