Quality Control

Our Ethyl (4-Isocyanatophenyl)Acetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets exacting standards for research and development. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry, well-ventilated place. Due to its highly volatile and easily oxidized nature, containers must be kept tightly sealed and away from heat, sparks, and open flame. Keep separated from incompatible materials such as strong acids, bases, alcohols, amines, and moisture.
