Triclocarban is an antimicrobial agent frequently used in personal care products with potential activity for endocrine disrupting, and hence its monitoring is particularly important. A sensitive anal. tool was developed for electroanal. of triclocarban by modifying a glassy carbon substrate with nitrogen-doped graphene quantum dots immobilized in chitosan. Electron microscopy results showed that the synthesized quantum dots had a diameter of 4.5 nm. The doping with nitrogen in the graphene matrix was confirmed by spectroscopic techniques. Electrochem. techniques showed excellent triclocarban oxidation current responses provided by the modified electrode compared to the bare electrode. The calibration plot for triclocarban was constructed in 0.1 mol L-1 phosphate buffer (pH 7.0):ethanol (95:5 volume/volume) in the range of 0.05 to 8.0μmol L-1 with limits of detection and quantification of 17.0 and 57.0 nmol L-1, resp. The modified electrode was effectively implemented in the quantification of triclocarban in personal care products with recoveries data in the range of 90 to 109%. Furthermore, the modified electrode was applied in the simultaneous determination of triclosan (+0.60 V) and triclocarban (+0.95 V) with limits of detection of 14.0 and 21.0 nmol L-1, resp. The application was carried out in surface water samples with excellent accuracy indicated by recovery data in the range of 93 to 110%. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Product Details of 101-20-2).
1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Product Details of 101-20-2
