Observed n 閳?锜? bands in the ultraviolet absorption solution spectra of the biazanaphthalenes was written by Hirt, R. C.;King, F. T.;Cavagnol, J. C.. And the article was included in Journal of Chemical Physics in 1956.Application of 5448-43-1 This article mentions the following:
Weak bands were observed in the ultraviolet absorption solution spectra of phthalazine, quinoxaline, 6-chloroquinoxaline, and 6-bromoquinoxaline, which show “blue-shifts” in a more polar solvent sequence. These bands, along with those reported for cinnoline, were assigned as n 閳?锜? bands analogous to those of the diazines and triazines. In the experiment, the researchers used many compounds, for example, 6-Chloroquinoxaline (cas: 5448-43-1Application of 5448-43-1).
6-Chloroquinoxaline (cas: 5448-43-1) belongs to quinoxaline derivatives. Compounds possessing quinoxaline derivatives were bestowed with a variety of significant biological properties such as antiviral, antimalarial, anticancer, DNA intercalation, DNA duplex stabilization, and many others. Quinoxalines are used in the treatment of bacterial, cancer, and HIV infections. Moreover, varenicline, a clinical drug is used for treating nicotine addiction, also contains quinoxaline moiety.Application of 5448-43-1
