Description

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.

Low-Energy Collisions of Protonated Enantiopure Amino Acids with Chiral Target Gases.

K Kulyk et al.

Journal of the American Society for Mass Spectrometry, 28(12), 2686-2691 (2017-09-25)

Here we report on the gas-phase interactions between protonated enantiopure amino acids (L- and D-enantiomers of Met, Phe, and Trp) and chiral target gases [(R)- and (S)-2-butanol, and (S)-1-phenylethanol] in 0.1-10.0 eV low-energy collisions. Two major processes are seen to

Hematopoietic α7 nicotinic acetylcholine receptor deficiency increases inflammation and platelet activation status, but does not aggravate atherosclerosis.

S Kooijman et al.

Journal of thrombosis and haemostasis : JTH, 13(1), 126-135 (2014-10-28)

The autonomic nervous system attenuates inflammation through activation of the α7 nicotinic acetylcholine receptor (α7nAChR), a pathway termed the cholinergic anti-inflammatory reflex. Interestingly, α7nAChR is expressed on immune cells and platelets, both of which play a crucial role in the
