In the title molecule, C18H20F2N2O2S, the 2,6-difluoro-4-hydroxyphenyl ring and the carbonylthiourea group are each essentially planar, with maximum deviations of atoms from their mean planes of 0.0113 (14) and 0.1017 (15) Å, respectively; the dihedral angle between these two planes is 71.03 (6)°. An intramolecular N—H
O hydrogen bond occurs. In the crystal, N—HO and O—HS hydrogen bonds connect the molecules into chains running diagonally across the bc plane. C—HS and C—HF contacts are also observed.
