Quality Control

Our 2,5-Dimethylterephthalonitrile is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency that meets the demanding requirements of our industrial and research clients. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
