Quality Control

Our 1,3-Bis(Isocyanatomethyl)Benzene is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets exacting industry standards. Certificates of Analysis (COA) documenting all critical parameters 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 a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture ingress.
