Quality Control

Our 2-Ethylphenyl Isocyanate undergoes rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques including GC, HPLC, and NMR to verify identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) detailing batch-specific results are available upon request 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 temperatures between 15-25°C (59-77°F). This product is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation and polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
