2R3R23dibromobutane

2,3-Dibromobutane is an organic chemical compound with the molecular formula C4H8Br2. It is a dibromoalkane, meaning it is an alkane with two hydrogen atoms replaced by bromine atoms. The "2,3" in its name indicates that the bromine atoms are attached to the second and third carbon atoms of the butane chain.

This compound exists as several stereoisomers due to the presence of two chiral centers at the second and third carbon atoms. These stereoisomers include enantiomers and diastereomers. Specifically, it can exist as the (2R,3R) enantiomer, the (2S,3S) enantiomer, and a pair of diastereomers, (2R,3S) and (2S,3R), which are meso compounds. The specific isomer 2R3R23dibromobutane refers to a particular stereochemical configuration of this molecule.

2,3-Dibromobutane is typically synthesized through the bromination of butene. It can be used as a precursor in organic synthesis, for example, in the preparation of other butane derivatives or in elimination reactions to form unsaturated hydrocarbons. Its physical properties, such as boiling point and density, are characteristic of halogenated hydrocarbons. Like many organobromine compounds, it should be handled with care due to potential toxicity.
