Sign in to saveAlso known as n-propyl bromide, 1-bromopropane, bromopropane
1-Bromopropane (also known as '''n-propyl bromide or nPB''') is a bromoalkane with the chemical formula CH3CH2CH2Br. It is a colorless, flammable 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. It was also used as a dry cleaning solvent as a substitute for perchloroethylene for a short time in the United States. 1-Bromopropane is highly neurotoxic to humans.

== Preparation == Industrial routes to 1-bromopropane involve free-radical additions to the corresponding alkenes. In this way, the anti-Markovnikov product is obtained. Alternatively, n''propanol may be substitutively brominated. The latter reaction is also viable laboratory synthesis.
