CAS 23138-50-3

1-Ethyl-4-isocyanatobenzene

Description:

1-Ethyl-4-isocyanatobenzene, also known by its CAS number 23138-50-3, is an organic compound that features both an ethyl group and an isocyanate functional group attached to a benzene ring. This compound is characterized by its aromatic structure, which contributes to its stability and reactivity. The presence of the isocyanate group (-N=C=O) makes it a versatile intermediate in organic synthesis, particularly in the production of polyurethane materials and other nitrogen-containing compounds. It is typically a colorless to pale yellow liquid with a distinct odor. The compound is known to be reactive, especially with nucleophiles, and can undergo various chemical reactions, including polymerization and substitution reactions. Safety precautions are essential when handling this substance, as isocyanates can be hazardous, causing respiratory irritation and sensitization. Proper storage and handling in a well-ventilated area with appropriate personal protective equipment are recommended to mitigate exposure risks.
