The 4-(1′-cyanoisoindolyl)phenylisothiocyanate (CIPIC) could be used as a chemiluminescence (CL) Edman-type reagent. Firstly, CL reaction conditions such as pH, buffer types, H 2 O 2 concentration and organic solvents were optimized in detail. Secondly, the CL sensitivity of the derivative of Ala was compared with fluorescence and absorbance detections. Thirdly, the structures of the...
We report analytical informations on the quantification of cefaclor (CCL), a β-lactam antibiotic by three detection methods. The methods were based on the chemical derivatization of the drug with 4-(2'-cyanoisoindolyl)phenylisothiocyanate (CIPIC) under the reaction conditions with heating at 80 o C for 7 min in the presence of pyridine. The CIPIC reagent could react with the primary amino...
