Quality Control

Our N,N'-Methanetetraylbis[4-[(4-Isocyanatophenyl)Methyl]-Benzenamin is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure consistent purity, reactivity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, isocyanate content, and impurity profiles is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 25°C. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
