Quality Control

Our 2,5-Diiodo-1,4-Benzenedicarboxaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from incompatible materials such as strong oxidizing agents.
