Description

Application

(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.

(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.
•  2-butyl tosylate building block by reacting with toluenesulfonyl chloride.

Packaging
