4-Methylphenyl isocyanate

Description:

4-Methylphenyl isocyanate, also known as p-tolyl isocyanate, is an organic compound characterized by the presence of an isocyanate functional group (-N=C=O) attached to a para-substituted methylphenyl ring. Its molecular formula is C8H9N, and it features a relatively low molecular weight. This compound is typically a colorless to pale yellow liquid with a pungent odor, indicative of its reactivity. 4-Methylphenyl isocyanate is known for its role in the synthesis of various pharmaceuticals, agrochemicals, and polymers, particularly in the production of urethane compounds. It is highly reactive, especially with nucleophiles, and can undergo polymerization or form adducts with amines and alcohols. Due to its isocyanate group, it poses health hazards, including respiratory irritation and potential sensitization, necessitating careful handling and appropriate safety measures in laboratory and industrial settings. Its applications and reactivity make it a significant compound in organic synthesis and materials science.
