description In the title pyridine herbicide {systematic name: 2-[(4-amino-3,5-di­chloro-6-fluoro­pyridin-2-yl)­oxy]acetic acid}, C(7)H(5)Cl(2)FN(2)O(3), the mean plane of the carb­oxy­lic acid substituent and the pyridyl ring plane subtend a dihedral angle of 77.5 (1)°. In the crystal, pairs of O—H⋯O hydrogen bonds form inversion dimers with R (2) (2)(8) ring motifs. These are extended into chains along [011] by N—H⋯F hydrogen bonds. In addition, inter­molecular N—H⋯O hydrogen bonds and weak π–π inter­actions [ring centroid separation = 3.4602 (9) Å] connect these chains into a three-dimensional network.
