Quality Control

Our production of 5-[Bis(1-Isocyanato-1-Cyclohexa-2,4-Dienyl)Methyl]-5-Isocyanato-Cyclohexa-1,3-Diene adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay, purity profiling, and impurity quantification, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting full test results are provided with each shipment.

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 (or as specified on the label) to minimize degradation and polymerization. Due to its hygroscopic (moisture-sensitive) and highly volatile nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
