Quality Control

Our Butyl Isocyanate is produced and handled under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including assay by GC or HPLC and impurity profiling, to ensure it meets the high-purity standards required for industrial and research applications. A Certificate of Analysis (COA) detailing specific results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and moisture-sensitive nature, store under a dry, inert atmosphere (e.g., nitrogen) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to maximize stability. Keep away from heat, open flames, and strong bases.
