Fragmentation studies, using the El-ionization, high-resolution acquisition mode, of testosterone analogs (6-hydroxytestosterone, 5[alpha]-androstan-3[alpha]-ol-17-one, 5[alpha]-androstan-3[beta],17[beta]-diol, and
17-epitestosterone) derivatized into the corresponding TMS-enol-TMS-ethers allowed us to correlate specific fragments with precise chemical structures:
