Quality Control

Our (Isocyanatomethyl)Cyclopropane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation and polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
