The title compound, C10H15NO, has two mol-ecules in the asymmetric unit. Each mol-ecule has a near-planar C8NO unit excluding H atoms and the terminal methyl groups on the di-ethyl-amino groups, with mean deviations from planarity of 0.036 and 0.063 Å. In the crystal, hydrogen bonding leads to four-membered O-H⋯O-H⋯O-H·· rings. No π-π inter-actions were observed in the structure.
Keywords: crystal structure; hydrogen bonding; phenols.
