Quality Control

Our Norbornene Diisocyanate is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including assay, purity profiling, and impurity identification, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified for specific grades. This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation and polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and water.
