4-[3-(2H-Benzotriazol-2-yl)propoxy]-3-methoxybenzaldehyde

In the title compound, C17H17N3O3, the 3-methoxybenzaldehyde group and the benzotriazole fragment are connected through a flexible oxypropyl chain. The O—C—C—C torsion angle in the central link is 63.9 (2)°, while the plane of the benzene ring of the 3-methoxybenzaldehyde substituent forms a dihedral angle of 56.4 (4)° with the benzotriazole plane.
