Abstract: The asymmetric unit of the title compound, C18H18ClN3OS·C2H5OH, comprises a pyrazoline derivative and an ethanol solvent molecule. In the molecule of the pyrazoline derivative, the pyrazole ring adopts an envelope conformation with the C atom bearing the ethoxyphenyl substituent as the flap. The dihedral angle between the benzene rings is 74.22 (7)°. The ethoxy group is coplanar with the attached benzene ring [C-O-C-Cmethyl = 175.50 (11)° and r.m.s. deviation = 0.0459 (1) Å for the nine non-H atoms]. In the crystal, the pyrazoline molecules are linked by N-HOethoxy hydrogen bonds into chains along the c axis and are further linked with the solvent ethanol molecules by N-HOethanol and Oethanol-HS hydrogen bonds. C-H interactions are also present.
