Quality Control

Our production of 5,5'-(1,3,4-Oxadiazole-2,5-Diyl)Diisophthalic Acid adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, 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 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 such as strong bases and oxidizing agents.
