Quality Control

Our 2-Chloro-3-Fluorophenylisocyanate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its moisture-sensitive and light-sensitive nature. Keep away from strong bases and incompatible materials such as alcohols, amines, and water.
