Cas no 1184937-05-0 (4-chloro-3-fluorophenyl chloroformate)

4-Chloro-3-fluorophenyl chloroformate is a reactive chloroformate ester widely used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. Its key advantages include high reactivity with nucleophiles, enabling efficient derivatization of amines, alcohols, and thiols to form carbamates, carbonates, and thiocarbonates, respectively. The presence of both chloro and fluoro substituents enhances its electrophilic character, facilitating selective reactions under mild conditions. This compound is valued for its stability under controlled storage conditions and its utility in introducing the 4-chloro-3-fluorophenyl moiety into complex molecular frameworks. Proper handling under inert atmospheres is recommended due to its moisture sensitivity.
