1-Bromopropane (n-propylbromide or nPB) is a bromoalkane with the chemical formula CH3CH2CH2Br. It is a colorless liquid that is used as a solvent. It has a characteristic hydrocarbon odor. Its industrial applications increased dramatically in the 21st century due to the phasing out of chlorofluorocarbons and chloroalkanes such as 1,1,1-trichloroethane under the Montreal Protocol.
