Quality Control

Our tert-Butylisocyanate is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including GC, HPLC, and IR spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container must be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
