The title compound, {systematic name: 1-[3-({[(4,6-dimethoxypyrimidin-2-yl)carbamoyl]amino}sulfonyl)pyridin-2-yl]-2-fluoropropyl 2-methoxyacetate}, C18H22FN5O8S, is used as a herbicide (pyrimidinylsulfonylurea herbicide). The dihedral angle between the mean planes of the pyridine and pyrimidine rings is 86.90 (7)°. In the crystal, N/C—H...O hydrogen bonds, C—H...F and C—H...π interactions link adjacent molecules, forming a chain along [020]. A further two C—H...O hydrogen bonds together with weak π–π interactions [ring centroid separation = 3.7584 (12) Å] further aggregate the structure into a three-dimensional architecture.
