4-Chloro-3-methylphenyl isocyanate

Description:
4-Chloro-3-methylphenyl isocyanate is an organic compound characterized by the presence of an isocyanate functional group (-N=C=O) attached to a chlorinated aromatic ring. Its molecular structure features a chloro substituent at the para position and a methyl group at the meta position relative to the isocyanate group on a phenyl ring. This compound is typically a colorless to pale yellow liquid with a pungent odor, indicative of the isocyanate functional group, which is known for its reactivity, particularly with nucleophiles such as amines and alcohols. 4-Chloro-3-methylphenyl isocyanate is used in the synthesis of various pharmaceuticals and agrochemicals, as well as in the production of polyurethanes. It is important to handle this compound with care due to its potential toxicity and irritant properties, particularly to the respiratory system and skin.
