Quality Control

Our α-Methylbenzyl Isocyanate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or HPLC and impurity profiling, to ensure it meets exacting purity standards suitable for industrial and research applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C to minimize volatility and degradation. Due to its highly volatile and moisture-sensitive nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) and separated from strong bases, acids, and sources of heat or ignition.
