2-Bromopentane is a bromoalkane and isomer of bromopentane. It is a colorless liquid. 2-Bromopentane is chiral and thus can be obtained as either of two stereoisomers designated as (R)-2-bromopentane and (S)-2-bromopentane, or as a racemic 1:1 mixture of the two enantiomers.

Applications

2-Bromopentane is an organic synthetic compound that can be used for selective C–H alkylation with ruthenium catalysts. It is also used as an intermediate in organic synthesis.
