CAS 42601-04-7: 3,4-Difluorophenyl isocyanate
Description:3,4-Difluorophenyl isocyanate is an organic compound characterized by the presence of an isocyanate functional group (-N=C=O) attached to a phenyl ring that has two fluorine substituents at the 3 and 4 positions. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity, particularly in forming urethanes and other derivatives through nucleophilic addition reactions. The presence of fluorine atoms enhances its electrophilic character, making it a useful intermediate in organic synthesis, particularly in the pharmaceutical and agrochemical industries. 3,4-Difluorophenyl isocyanate is also notable for its potential toxicity and should be handled with care, as isocyanates can cause respiratory irritation and sensitization. Proper safety measures, including the use of personal protective equipment and working in a well-ventilated area or fume hood, are essential when working with this compound. Its unique properties make it a valuable building block in the synthesis of various chemical entities.
