Quality Control

Our production of [1,1':3',1''-Terphenyl]-2,2'',4,4'',5'-Pentacarboxylic Acid adheres to stringent quality management protocols. Every batch is characterized and purified to meet exacting research and industrial grade specifications, with purity typically exceeding 95% (HPLC). Identity and purity are confirmed via advanced analytical techniques including NMR, HPLC, and MS. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to ensure traceability and compliance with your project requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
