1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. The piperazine scaffold is often found in biologically active compounds in different therapeutic areas. These therapeutic areas include antifungals, antidepressants, antivirals, and serotonin receptor (5-HT) antagonists/agonists. Piperazine is formed as a co-product in the ammoniation of 1,2-dichloroethane or ethanolamine. These are the only routes to the chemical used commercially.Quality Control of 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid

2D lanthanide coordination polymers as multi-responsive luminescence sensors for selective and sensitive recognition of Cr(VI)/MnO4 anions and broad-spectrum detection of antibiotics was written by Yuan, Gang;Chen, Zi-Qi;Zhang, Chao;Xie, Zi-Yu;Liu, Shi-Yu;Meng, Xiao-Hang;Sun, Jing-Yu;Li, Xiu-Mei;Dong, Li-Hong;Hao, Xiang-Rong. And the article was included in Journal of Solid State Chemistry in 2022.Quality Control of 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid The following contents are mentioned in the article:

Three new Ln(III)-CPs, {[Ln2(HL)2(H2O)2]·H2O}n (Ln = La (1), Eu (2) and Tb (3); H4L = 1,1′-(ethane-1,2-diyl)bis(1H-imidazole-4,5-dicarboxylic acid)) were hydrothermally synthesized and characterized by elemental analyses, IR, TG, PXRD and single-crystal x-ray diffraction. These isostructural CPs display 2D layer-like structures with a TiS2 topol. constructed from inter-connected cage-like SBBs. The Eu-CP and Tb-CP exhibit characteristic luminescent emissions based on metal ions and possess selective recognition ability toward Cr(VI) and MnO4 ions in aqueous solution They can also act as broad-spectrum fluorescent probes to detect common antibiotics. Furthermore, the fluorescence quenching mechanisms of two CPs were also studied in detail by combination of the PXRD patterns, UV-vis absorption spectra and theor. calculations This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Quality Control of 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid).
