Abstract: The racemic title compound, a new terpenoid, C₂₀H₂₉N₃O₂S·0.5C₄H₈O₂, was synthesized from Cedrus Atlantica essential oil. The compound crystallizes with a disordered ethyl acetate solvent molecule. The thiadiazole ring is almost planar, with a maximum deviation from the mean plane of 0.015 (2) Å for the C atom connected to the isobutyl group and has a puckering amplitude of 0.026 (2) Å. The dihedral angle between the benzene and thiadiazole rings is 18.32 (8)°. The crystal packing involves intermolecular N-HO hydrogen bonds.
