1,4-Dibromobutane is used as an intermediate involved in the synthesis of active pharmaceutical ingredient and other organic compounds. It is also used in the investigation of metabolism of two halopropanes such as 1,3-dichloropropane and 2,2-dichloropropane. Further, it acts as a reagent to prepare diazadioxa oxovanadium(IV) macrocyclic complexes.
