Quality Control

Our production of 3-[(2-Isocyanatocyclohexyl)Methyl]-o-Tolyl Isocyanate adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by titration, determination of isocyanate (NCO) content, and analysis of key impurities such as hydrolysable chlorine and residual solvents. Certificates of Analysis (COA) detailing all specifications and test results are provided and 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 8°C (refrigerated) to maximize stability and shelf-life. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent reaction with atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, acids, and water.
