1,4-Dibromobutane

1,4-?????? C??? ??, ??, ??

??? ??

Clear, colorless liquid

??

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.

?? ??

1,4-Dibromobutane reaction with atactic poly(2-vinylpyridine) leads to the formation of long-range 3D molecular ordering in polymer chains.
