Abstract: | Some intriguing discoveries were made concerning the collision-activated dissociation behavior of the derivatized car☐ylate anions of PGE2 and PGF2α. The car☐ylate anion [M-PFB]− formed from electron-capture negative chemical ionization of the pentafluorobenzyl ester-trimethylsilyl derivative of PGF2α showed little fragmentation under typical collision gas pressures and energies (<2.0 mtorr N2 and <20 eV). In contrast, the daughter spectra of the car☐ylate anion of the methoxime-pentafluorobenzyl ester-trimethylsilyl derivative of PGE2 produced many intense fragments under the same conditions. |
