Quality Control

Every batch of [1,1':4',1''-Terphenyl]-2',3,3'',5,5''-Pentacarboxylic Acid is manufactured under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR, and mass spectrometry to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your R&D and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect purity and performance. Keep away from incompatible materials.
