4-(Dimethyl­amino)benzaldehyde

The title compound, C(9)H(11)NO, crystallizes with two independent but essentially identical mol­ecules in the asymmetric unit, which are linked via a C—H⋯π inter­action. In both mol­ecules, the aldehyde and dimethyl­amine groups are essentially coplanar with the attached benzene ring. In the crystal structure, C—H⋯O hydrogen bonds link one type of independent mol­ecules into a chain along the a axis. In addition, the structure is stabilized by π–π stacking inter­actions involving the benzene rings [centroid-to-centroid distance = 3.697 (2) Å].
