The title compound, C19H17ClN2O5, is an important intermediate for the synthesis of the pesticide Indoxacarb [systematic name: (S)-methyl 7-chloro-2-{[(methoxycarbonyl)[4-(trifluoromethoxy)phenyl]amino]carbonyl}-2H,3H,4aH,5H-indeno[1,2-e][1,3,4]oxadiazine-4a-carboxylate] The C=N double bond has a Z conformation. An intramolecular N—HO hydrogen bond occurs. In the crystal structure, O—HO hydrogen bonds result in the formation of 12-membered rings lying about inversion centers with R44(12) motifs.

In the title molecule, C11H10ClFO2, the benzene ring, the F atom and the O atom of the dihydropyran ring are essentially coplanar, with an r.m.s. deviation of 0.007 Å. The dihydropyran ring is in a half-chair conformation. In the crystal, molecules are linked by pairs of weak C—Hπ hydrogen bonds, forming inversion dimers.

In the title compound, C7H9NO2, all non-H atoms are essentially coplanar [r.m.s. deviation = 0.032 Å]. The largest deviation from the plane of the pyridine ring is 0.105 (6) Å for the terminal C atom of the ethoxy group. In the crystal, molecules are linked by pairs of N—HO hydrogen bonds, forming inversion dimers. These dimers are further linked by C—Hπ interactions and weak π–π interactions between pyridine rings [centroid–centroid distance = 4.023 (1) Å].
