A systematic study of the mass spectral fragmentation of the methyl ester-methyloxime-trimethylsilyl ether derivatives of D and E prostaglandins and selected ω-chain analogs is presented. Fragments from the ω-chain analogs are shifted the appropriate mass when compared with the parent PGD2 or PGE2. NMR data of the methyloxime methyl ester of PGE2 have permitted assignment of the syn and anti isomers (relative to the α chain) to the fast and slow eluting gas chromatographic peaks, respectively.
