2-Amino-4-(4-hydroxyphenyl)-5-propylthiazole was synthesized by the reaction of α-bromo-1-(4-hydroxyphenyl)-1-pentone with thiourea. The crystal structure of its ethanol solvate 0.25 hydrate, C12H14N2OS···C2H5OH···0.25·H2O, was determined by X-ray diffraction analysis. The crystal belongs to monoclinic system, space group C2/c with a = 20.9046(10), b = 10.1057(5), c = 30.0017(15) Å, β = 105.5850(10)°, Z = 8, M r = 569.77, V = 6105.0(5) Å3, D c = 1.240 g/cm3, μ = 0.214 mm−1, F(000) = 2440, the final R = 0.0598 and wR = 0.1825 for 5,911 observed reflections [I > 2σ(I)]. Compound (1) is composed by two non-coplanar ring systems of phenol and thiazole. The structure displays extensive O–H···N, N–H···O and O–H···O intermolecular hydrogen bonds. 2-Amino-4-(4-hydroxyphenyl)-5-propylthiazole was synthesized by the reaction of α-bromo-1-(4-hydroxyphenyl)-1-pentone with thiourea and the crystal structure of its ethanol solvate 0.25 hydrate, C12H14N2OS···C2H5OH···0.25·H2O, was determined by X-ray diffraction analysis.
