A. Ferretti et al., MASS-SPECTRA OF N-BUTYLBORONATE ESTER DERIVATIVES OF THE MAJOR METABOLITE OF PROSTAGLANDIN-F, Organic mass spectrometry, 29(7), 1994, pp. 360-365
The El mass spectra of six n-butylboronate ester derivatives of the ma
jor metabolite of prostaglandins F1alpha and F2alpha (PGF-M) are prese
nted and discussed. Proposed ion assignments and fragmentation pathway
s are based on substituent shifts, on data from a deuterium-labeled me
thoxime derivative and on the analysis of collision-induced dissociati
on spectra of selected ions. Fragment ions suitable for identification
and quantification of PGF-M in a biological matrix and diagnostically
valuable ions for structure recognition are proposed.
