Quality Control

Our Bis(2-Isocyanatoethyl) Carbonate is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including HPLC, titration, and spectroscopic methods. A Certificate of Analysis (COA) detailing purity, isocyanate content, 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 a dry inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Due to its highly volatile and easily oxidized nature, the container must be kept tightly sealed when not in use to prevent moisture ingress, polymerization, and degradation. Recommended storage temperature is 2-8°C for long-term stability.
