Abstract: | The kinetics decomposition of 2-chloroethylnitrososulfamides (CENS) was studied in aqueous buffered solutions with pH ranging from 0 to 14. The study was monitored by RP-LC-MS and conventional UV spectrophotometry. The reaction proceeded via a pseudo-first-order kinetic with significant correlation coefficient. The major decomposition products from CENS after incubation in phosphate buffer were isolated and identified by NMR and mass spectrometry. The results indicate that the mechanism pathway involves a denitrosation of the CENS and competitive hydrolysis with nucleophilic attack on the sulfur atom and formation of sulfamate compounds. |
