Quality Control

Our 5-Chloro-2-Methylphenyl Isocyanate undergoes rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques including HPLC, GC, and NMR to verify identity, purity, and impurity profiles. Certificates of Analysis (COA) are available upon request, providing full traceability and batch-specific data 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture ingress. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and strong bases.
