Quality Control

Our Benzene, 2-Isocyanato-1-Methyl-4-(1-Methylethyl)- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, purity profiling, and identification, to ensure it meets exacting standards for research and industrial use. 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong bases and incompatible organic solvents.
