24Dibromopentane

2,4-Dibromopentane is an organic chemical compound with the molecular formula C5H10Br2. It is a halogenated alkane, specifically a dibrominated derivative of pentane. In this molecule, bromine atoms are attached to the second and fourth carbon atoms of the five-carbon chain. It is a colorless liquid at room temperature and pressure. Like many organobromine compounds, it is generally insoluble in water but soluble in organic solvents such as ethanol and ether.

The synthesis of 2,4-dibromopentane can be achieved through various chemical reactions. One common method involves the bromination of pentane under specific conditions, or through the addition of bromine to alkenes like 2-pentene. The precise isomer, 2,4-dibromopentane, is obtained by controlling the regioselectivity of the reaction. This compound can exhibit stereoisomerism due to the presence of chiral centers at the second and fourth carbon atoms, potentially existing as diastereomers.

2,4-Dibromopentane finds use as a chemical intermediate in organic synthesis. Its reactive carbon-bromine bonds make it a valuable starting material for the preparation of other organic compounds through nucleophilic substitution or elimination reactions. It can be employed in the synthesis of cyclic compounds or other substituted alkanes. Safety precautions should be taken when handling 2,4-dibromopentane, as organobromine compounds can be irritating and toxic.
