In the title compound, C20H22N2O3·0.25H2O, the water molecule (occupancy 0.25) is disordered across a crystallographic inversion center. The dihedral angle between the hydroxyphenyl ring and the benzimidazole ring system is 59.31 (9)°. In the crystal structure, molecules are connected by intermolecular O—HN and C—HO hydrogen bonds. The crystal structure is further stabilized by a weak C—Hπ interaction involving the imidazole ring.
