6-Fluoro-1-(4-fluorophenyl)-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 98105-99-8) belongs to piperazine derivatives. Industrial applications of piperazine include the manufacture of plastics, resins, pesticides and brake fluids. Outside the body, piperazine has a remarkable power to dissolve uric acid and producing a soluble urate, but in clinical experience it has not proved equally successful.

A simple and an available method is proposed for the determination of quinolone antibiotics using solid-phase fluorescence digital colorimetry. The intrinsic fluorescence of 17 quinolones and the quinolone-sensitizedfluorescence of europium on cellulose paper (CP) and a thin silica layer are studied. Upon the irradiation of quinolone solutions applied to a matrix with UV light (365 nm), blue (CP, high-performance thin-layer chromatog. (HPTLC)) and pink (CP-Eu, HPTLC-Eu) fluorescence is observed Measurement of the fluorescence intensity on the surface of matrixes is carried out using a smartphone. The values of colorimetric parameters in the RGB system are used as the anal. signal (Ar): Ar = (R0-Rx)2 + (G0-Gx)2 (B0-Bx)2 The limits of detection and determination are 0.2-4 and 0.6-12 μg/mL, resp., for all analyzed analytes. The anal. ranges are 0.6-500 μg/mL. A procedure for the determination of fluoroquinolones in medicinal preparations is proposed. The relative standard deviation of the results of anal. does not exceed 5%. In the experiment, the researchers used many compounds, for example, 6-Fluoro-1-(4-fluorophenyl)-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 98105-99-8Related Products of 98105-99-8).
