Abstract: There are two nearly identical molecules in the asymmetric unit of the title compound, C₇H₇NO. The molecules are nearly planar (r.m.s. deviations of 0.025 and 0.017 Å) and oriented at a dihedral angle of 28.98 (3)°. The two molecules are linked by a C-HO hydrogen bond. In the crystal, weak intermolecular C-HO hydrogen bonds link the molecules into zigzag chains along the c axis.
