Quality Control

Every batch of 2-Dodecyl-1,3-Phenylene Diisocyanate is manufactured and tested under strict quality management protocols to ensure consistent purity and performance. Our quality assurance includes comprehensive analytical testing, and a Certificate of Analysis (COA) detailing key specifications such as assay, isocyanate content, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from strong bases and incompatible organic solvents.
