Quality Control

Our 4-Chloro-6-Methyl-m-Phenylene Diisocyanate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay by titration and impurity profiling by HPLC/GC, to ensure it meets precise specifications for industrial polymerization. Certificates of Analysis (COA) documenting purity, NCO content, and hydrolyzable chloride levels are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its moisture-sensitive (hygroscopic) and highly volatile nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and polymerization. Keep away from strong bases and organic solvents.
