Quality Control

Our 3 4-Dichlorophenethyl Isocyanate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including chromatography and spectroscopy, to confirm identity and assay. A Certificate of Analysis (COA) detailing purity, impurities, and physical parameters is provided with every shipment 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, as the product is both hygroscopic (moisture-sensitive) and light-sensitive. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases. Allow the container to reach ambient temperature before opening to prevent moisture condensation.
