Quality Control

Our [1,1':3',1''-Terphenyl]-3,3'',5,5''-Tetracarboxylic Acid is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure high purity and batch-to-batch consistency, critical for research reproducibility and industrial process stability. A detailed Certificate of Analysis (COA) providing specifications for identity, purity (typically by HPLC), and impurity profiles is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed under dry, inert conditions to prevent moisture absorption, which can affect purity and performance. Recommended long-term storage temperature is 2-8°C.
