We report a synthesis of 3-bromo-9-N′-(N,N-dimethylformamidino)benzanthrone in good yield by condensation reaction 3-bromo-9-aminobenzanthrone with dimethylformamide the presence phosphorous oxychloride. The structure synthesized amidine was characterized FTIR-ATR, NMR experiments, and elemental analysis. title compound analyzed UV-Vis fluorescence spectroscopy various organic solvents.

In the title mol-ecule, C(51)H(46)BrN(3), the central fluorene residue is planar (r.m.s. deviation = 0.0203 Å), as is the carbazole system (r.m.s. deviation = 0.0154 Å), and these groups are almost orthogonal [dihedral angle = 79.72 (3)°]. The three-dimensional architecture is consolidated by C-H⋯π inter-actions. The butyl substituent is disordered with two sites resolved for the terminal propy...

A sweeping technique, in conjunction with micellar electrokinetic chromatography, for the simultaneous determination of flunitrazepam and its major metabolites, 7-aminoflunitrazepam and N-desmethylflunitrazepam, is described. The optimized conditions for the sweeping and separation were a pH 9.5 buffer, 25mM borate, 50mM cetyltrimethylammonium bromide, 30% MeOH (v/v), and a 151-mm injection len...
