Quality Control

Our Benzene, 1-Fluoro-4-[(1E)-2-Isocyanatoethenyl]- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and FTIR, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, guaranteeing compliance with your research or production specifications.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation by moisture. Keep away from heat, sparks, and open flame.
