Pentyl isocyanate is an organic chemical compound of carbon, hydrogen, nitrogen, and oxygen with the linear formula CH3(CH2)4NCO.[2][3][4]
The most common industrial route to obtain the compound involves reacting n-pentylamine with phosgene.[5] The reaction typically occurs in an inert organic solvent (like chlorobenzene) to form a carbamoyl chloride intermediate, followed by heating (100–200 °C) to complete the conversion and remove hydrogen chloride (HCl).
