The crystal structure of the title compound, C₇H₇NO₃, shows a strong quinoid character. The oximic function is anti with respect to the methoxy group so that no intramolecular hydrogen bonds involving the acidic H atom are formed, instead a strong intermolecular interaction is favoured. Two molecules are present in the asymmetric unit and they show no significant differences in their bond lengths and angles, but they do have different packing interactions.
