1,3-Dibromobut-2-ene is a halogenated alkene featuring a four-carbon chain with bromine atoms at the 1- and 3-positions and a double bond between the 2- and 3-carbons. Its reactive bromine substituents and unsaturation make it useful as an intermediate in organic synthesis, particularly for forming carbon–carbon and carbon–heteroatom bonds.
