Abstract The mass spectral fragmentations of a number of steroidal 3,5‐ and 4,5‐diols and some derivatives have been examined using high resolution mass spectrometry and deuterium labelling. Although the 3,5‐ and 4,5‐diols have very similar mass spectra those of the derived ketols are quite characteristic. A pathway for the formation of the important m / e 332 ion in the mass spectrum of cholestan‐4β,5α‐diol has been postulated.
