Quality Control

Our 1,4-Benzenedicarboxylic Acid, 2,5-Bis(Methylamino)- is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 sealed under dry conditions to prevent product degradation. Keep away from incompatible materials such as strong oxidizing agents.
