Quality Control

Our production of 4-Cyclohexene-1,2-Dicarboxylic Acid Bis(2-Isocyanatoethyl) Ester adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, isocyanate content, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and reacts with strong bases and organic solvents; ensure containers are sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and premature polymerization. Keep away from heat, sparks, and open flame.
