Quality Control

Our sec-Butyl Isocyanate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, assay, and impurity profiles. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases, alcohols, and amines. Due to its highly volatile nature, containers should be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) when not in use to maintain purity and prevent moisture ingress. Recommended storage temperature is 2-8°C.
