애플리케이션

(R)-(−)-2-Butanol can be used as a reagent in the synthesis of:
  • 1-[(S)-2-butyl]-3,5 diphenyl-1H-1,2,4 triazole from 3,5 diphenyl-1H-1,2,4 triazole by Mitsunobu reaction.[1]
  • 2-butyl tosylate building block by reacting with toluenesulfonyl chloride.[2]

(R)-(-)-2-Butanol has been used as a freeze drying medium during the long term cryopreservation of smooth muscle cells samples in a freezing container.[3]
