Quality Control

Our Trimethyl-1,6-Hexamethylene Diisocyanate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay, isocyanate content, and impurity profile analysis, to ensure it meets precise specifications for industrial and research applications. A Certificate of Analysis (COA) detailing all quality parameters is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area under an inert atmosphere (e.g., nitrogen) to prevent oxidation and moisture absorption. Recommended storage temperature is 2-8°C to maintain stability and minimize volatility. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
