Quality Control

Our production of 2-[(3-Isocyanato-2-Methylphenyl)Methyl]-m-Phenylene Diisocyanate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay (isocyanate content), purity by HPLC, and control of key impurities like hydrolyzable chlorine, to ensure consistent performance and reliability for your formulations. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, well-ventilated area at temperatures recommended for isocyanates (typically 15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) after initial opening to prevent reaction with atmospheric moisture and CO2.
