Quality Control

Our 1,1'-(2-Isocyanocyclopropylidene)Bisbenzene is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to the reactivity of the isocyanate group, the container must be kept under an inert atmosphere (e.g., nitrogen or argon) and protected from moisture to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
