Structural characterization of the regioisomers of di(hydroxybutyl) ether by GC-EI MS and theoretical calculations.

Abstract

Di(hydroxybutyl) ether (DHBE), a liver protecting drug, is composed of a mixture of three regioisomers: 4-(3-hydroxybutoxy)-2-butanol (1), 3-(4-hydroxy-2-butoxy)-1-butanol (2), and 3-(3-hydroxybutoxy)-1-butanol (3). Unequivocal differentiation of each regioisomer of DHBE was rapidly obtained without isolation of the single components, using GC-MS with… (More)
