Exploring the crystal and molecular structures of methenolone and drostanolone enanthate

Methenolone and drostanolone are two popular synthetic anabolic-androgenic agents and dihydrotestosterone derivatives which belong to the steroid family. Two esterified prodrugs of methenolone and drostanolone, in the form of methenolone and drostanolone enanthate, have been described from a structural point of view. The crystal structure of drostanolone enanthate was determined by single crystal X-ray diffraction, while the crystal structure of methenolone enanthate was solved by the powder X-ray diffraction technique. The nature and magnitudes of intermolecular interactions were analysed quantitatively by means of crystal lattice energies and Hirshfeld surfaces.
