Abstract: The title compound, C₂₁H₂₈O₃, is a steroid derivative used as an intermediate in medicine. The molecular structure corresponds to an earlier determination [Goubitz et al. (1984). Steroids, 44, 153-158]. However, the orthorhombic unit-cell parameters of the two determinations are significantly different, and these structures are polymorphs.
