Quality Control

Our production of 2,6-Bis[2-Isocyanato-3-[(2-Isocyanatophenyl)Methyl]Benzyl]Phenyl Isocyanate adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including assay (by HPLC), determination of isocyanate content (NCO%), and analysis of key impurities, to ensure consistency and compliance with exacting customer specifications. Certificates of Analysis (COA) documenting purity, physical properties, and safety data are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F - 77°F). This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or argon) to prevent reaction with atmospheric moisture and carbon dioxide, which can lead to polymerization or urea formation. Keep away from strong bases, amines, alcohols, and other compounds containing active hydrogen.
