Clear pale yellow liquid | [Uses]
3-Bromopentane is a glass forming liquid used in the preparation of 2-(1-ethyl-propoxy)-isoindole-1,3-dione. Further, it is employed in organic synthesis. | [Preparation]
Isomerically pure 3-bromopentane could be prepared from tri-1-ethylpropyl phosphite and hydrogen bromide and solvolysed in 60% aqueous ethanol. The detection of about 1% rearrangement products in both acid and weakly alkaline conditions supports the view that carbonium ion intermediates are formed in the reaction of at least a proportion of the molecules[1]. | [General Description]
3-Bromopentane is a glass forming liquid. The dielectric relaxation of 3-bromopentane was studied. | [References]
