4-[2-(4-Hy­droxy­phen­yl)eth­yl]-3-propyl-1H-1,2,4-triazol-5(4H)-one

The asymmetric unit of the title compound, C13H17N3O2, contains eight crystallographically independent mol­ecules. The planes of the benzene and triazole rings in the eight mol­ecules make dihedral angles of 5.53 (13), 9.33 (13), 19.28 (11), 17.36 (8), 12.84 (12), 8.03 (8), 19.97 (11), and 7.98 (8)°. The eight mol­ecules in the asymmetric unit are linked by inter­molecular O—H⋯O and N—H⋯O hydrogen bonds, forming a three-dimensional network.
