| | (S)-1-Bromo-2-methylbutane Usage And Synthesis |
| Uses | (S)-(+)-1-Bromo-2-methylbutane, is used for the synthesis of chiral nematic liquid crystals and optically active Grignard reagents. | | Purification Methods | Wash the bromobutane with ice-cold H2O, dry by freezing, shake it twice with an equal volume of H2SO4 at 0o, and twice with an equal volume of H2O at 0o. Freeze-dry and keep over freshly heated (and then cooled) K2CO3, and distil it |
