Abstract: The indazole ring system of the title compound, C19H21N3O3S, is almost planar (r.m.s. deviation = 0.0192 Å) and forms dihedral angles of 77.99 (15) and 83.9 (3)° with the benzene ring and allyl group, respectively. In the crystal, centrosymmetrically related molecules are connected by pairs of N-HO hydrogen bonds into dimers, which are further linked by C-HO hydrogen bonds, forming columns parallel to the b axis.
