Quality Control

Our production of 5-[(4-Isocyanatocyclohexyl)Methyl]-o-Tolyl Isocyanate adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Every lot undergoes comprehensive analytical testing, including assay, isocyanate content, and impurity profiling. Certificates of Analysis (COA) documenting all critical parameters 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 temperatures between 2°C and 25°C. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and polymerization. Isolate from moisture, heat, and incompatible materials such as alcohols, amines, and strong bases.
