Application

(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.

(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.

The scavenger receptor CD36 facilitates the cellular uptake of long-chain fatty acids. As CD36-deficiency attenuates the development of high fat diet (HFD)-induced obesity, the role of CD36-deficiency in preadipocyte recruitment and adipocyte function was set out to characterize. Fat cell
