(R)-(-)-2-Amino-1-butanol Usage And Synthesis

Chemical Properties

clear colorless to light yellow viscous liquid

Purification Methods

They are purified by shaking with solid NaOH, filtering and distilling through a short column. The oxalate of the racemate has m 176o. They are strong bases and should be stored under N2 in the absence of CO2. The enantiomers have [] 20 ±12.5o (c 2, EtOH). [Johnson & Degering J Org Chem 8 7 1943, Nagao et al.
