Quality Control

Our production of 5-(o-Isocyanatobenzyl)-2-Methyl-m-Phenylene Diisocyanate adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and titration to confirm identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Isolate from moisture, heat, and incompatible materials such as alcohols, amines, and strong bases.
