1-Bromobutane is used as an intermediate in organic synthesis and as a solvent for cleaning and degreasing. It acts as an alkylating agent as well as to prepare organometallic compounds such as n-butyllithium. It is also involved in the synthesis of procaine and tetracaine. It reacts with magnesium metal to prepare the Grignard reagent, which is used to form carbon-carbon bonds.
