In the title compound, C(15)H(9)F(4)N(3)O(2)S, the N,N'-disubstituted thio-urea fragment adopts a cis,trans geometry, stabilized by an intra-molecular N-H⋯O hydrogen bond to the carbonyl O atom of the tetra-fluoro-benzoyl group. The central thio-urea group makes dihedral angles of 47.79 (7) and 35.54 (8)°

Hemoglobin adducts of the carcinogenic tobacco-specific nitrosamines 4-(methylnitrosamino)-1(3-pyridyl)-1-butanone and N'-nitrosonornicotine were quantified in blood samples collected from snuff dippers, smokers, and nonsmokers. Mild base treatment of hemoglobin adducted by 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone or N'-nitrosonornicotine releases 4-hydroxy-1-(3-pyridyl)-1-butanone (HPB). HPB was enriched by solvent
