چکیده
In the title compound, C(20)H(16)N(4)O, the non-H atoms of the benzotriazole ring system and those of the methyl-phenol group are essentially coplanar, with an r.m.s. deviation of 0.004 (2) Å. The mean plane of these atoms forms a dihedral angle of 60.9 (2)° with the phenyl ring. There is an intra-molecular O-H⋯N hydrogen bond between the phenol and benzotriazole groups.
