22537-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22537-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,3 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22537-40:
(7*2)+(6*2)+(5*5)+(4*3)+(3*7)+(2*4)+(1*0)=92
92 % 10 = 2
So 22537-40-2 is a valid CAS Registry Number.

Fluorescence probe enhanced spectrofluorimetric method for the determination of gatifloxacin in pharmaceutical formulations and biological fluids

Zhu, Xiashi,Gong, Aiqin,Yu, Suhai

, p. 478 - 482 (2008)

A spectrofluorimetry for the determination of gatifloxacin (GFLX) was developed based on the strong fluorescence of gatifloxacin after adding fluorescence probe yttrium in buffer solution (pH 7.0) and various factors of influencing fluorescence have been researched. Under the optimum conditions, the liner range was 4.00 × 10-8 to 1.00 × 10-6 g mL-1 and the detection limit is 3.36 × 10-9 g mL-1 (correlation coefficient r = 0.9997), respectively. The relative standard deviation was 1.1% for 11 measurements of 5.6 × 10-7 g mL-1 gatifloxacin standard solution. The mechanism of sensitizing effect of probe was discussed. The proposed method has been successfully applied to determine real samples and the obtained results are in good agreement with the results of HPLC.

Solvent extraction of some trace metals and iron with N-octyl-N,N- bis(dihexylphosphinylmethyl)amine

Cherkasov,Garifzyanov,Bazanova,Leont'eva

, p. 2080 - 2087 (2012/03/12)

The processes were studied of the solvent extraction of the ions of triply-charged trace elements including scandium, indium, gallium, and yttrium, as well as iron, with N-octyl-N,N-bis(dihexylphosphinylmethyl)amine solution in toluene, chloroform or methylene chloride from hydrochloric, nitric or perchloric acids aqueous solutions. The metals extraction dependence on the acid concentration showed that the best results were reached using perchloric acid. The calculation of partition coefficients of metals allowed us to reveal a high selectivity of the scandium extraction. The prospects of using the investigated bisphosphinylamine in the technology of extraction, concentration and separation of the trace metals ions was concluded. Pleiades Publishing, Ltd., 2011.

Effect of heptadentate (N4O3) tripodal Schiff base ligand and its yttrium(III) complex on the luminescence and extraction of tris(β-diketonato)europium(III)

Hasegawa,Saitou,Nagaoka,Yajima,Kanesato

, p. 320 - 324 (2009/01/21)

In order to learn the effect of a Schiff base and the complex of YIII on the extraction of EuIII with β-diketones and on the luminescence of the extracted species, the extraction of EuIII with 2-thenoyltrifluoroacetone (Htta) and/or these Schiff bases, tris(5-t-butyl)salicylidenaminoethyl amine (H3L1), and its YIII complex ([YL1]) prepared, into CHCl3 was examined. Further, the luminescence and excited spectra of CHCl3 phases extracted EuIII complexes and the solutions containing tris(β-diketonato)EuIII and/or the Schiff bases were measured. On the measurement of the luminescence spectra, tris(pivaloyltrifluoroacetonato)EuIII (Eu(pta)3) as well as Eu(tta)3 was used. Synergistic effect with Htta and these Schiff bases was observed. However, proper effect of YIII was not observed. The luminescence intensity of Eu(tta)3 at 613 nm decreased with increasing concentration of H3L1 or [YL1], whereas that of Eu(pta)3 increased with increasing concentration of the ligands, but no difference between both Schiff bases was observed, because of picking up of YIII from [YL1] with the interaction between [YL1] and water.
