Quality Control

Every batch of 2 2-Diphenylethyl Isocyanate 97 undergoes rigorous analytical testing to ensure it meets stringent purity and consistency standards. Our quality assurance protocol includes advanced chromatographic and spectroscopic methods to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing assay, purity, and specific impurity limits is provided with each shipment, ensuring full traceability and compliance for your quality management systems.

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 material is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and polymerization. Keep away from strong bases and incompatible materials such as alcohols, amines, and water.
