Cas no 23138-58-1 (1-ethyl-3-isocyanatobenzene)

1-Ethyl-3-isocyanatobenzene is an aromatic isocyanate compound characterized by its reactive isocyanate functional group attached to a benzene ring substituted with an ethyl group at the meta position. This compound is primarily utilized as a versatile intermediate in organic synthesis, particularly in the production of polyurethanes, coatings, adhesives, and specialty polymers. Its structure offers a balance between reactivity and stability, enabling controlled reactions with polyols, amines, and other nucleophiles. The ethyl substituent influences solubility and steric properties, making it suitable for tailored applications requiring specific performance characteristics. Proper handling is essential due to its potential sensitivity to moisture and reactivity hazards.
