Quality Control

Our 4-Chloro-2-Methylphenyl Isocyanate is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by HPLC, identification by FT-IR, and impurity profiling, to ensure it meets high-purity standards suitable for industrial and research applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen) to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and water.
