Crystal structure of pyriproxyfen

In the title compound {systematic name: 4-phen­oxy­phenyl (RS)-2-[(pyridin-2-yl)­oxy]propyl ether}, C(20)H(19)NO(3), which is a juvenile hormone mimic and insecticide, the dihedral angles between the plane of the central benene ring and those of the pendant pyridine ring and phenyl ring are 78.09 (6) and 82.14 (8)°, respectively. The conformation of the O—C—C—O linkage is gauche [torsion angle = −75.0 (2)°]. In the crystal, weak aromatic π–π stacking inter­actions [centroid–centroid separation = 3.8436 (13) Å] and C—H⋯π inter­actions link adjacent mol­ecules, forming a three-dimensional network.
