Quality Control

Our 2-Chloro-6-Methylphenyl Isocyanate is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment, ensuring full traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
