Quality Control

Our production of 2,2-Dimethylpentane-1,5-Diyl Diisocyanate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure high purity and consistency, meeting the exacting requirements of advanced polymer formulation. Certificates of Analysis (COA) detailing purity, isocyanate content, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or dry air) to prevent reaction with atmospheric moisture. Recommended storage temperature is 15-25°C. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and water.
