(-)-2-Butanol Use and Manufacturing

(-)-2-Butanol is an intermediate in drug synthesis and is also used as a freeze-drying medium during long-term cryopreservation of smooth muscle cell samples in freezing containers. (-)-2-Butanol can be used as a reagent to synthesize the following substances: 1-[(S)-2-butyl]-3,5-diphenyl-1H-1,2,4-triazole is generated from 3,5-diphenyl-1H-1,2,4-triazole through Mitsunobu reaction; and it reacts with toluenesulfonyl chloride to generate 2-butyl toluenesulfonate structural units.
