Quality Control

Our 1-Isocyanato-3-Methylbutane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to support your quality assurance protocols.

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, amines, and water. Due to its highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) when not in use to prevent moisture ingress and polymerization. Recommended storage temperature is 2-8°C for extended stability.
