New Advances in Chemical Research, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.Quality Control of 2,3-Dichloroquinoxaline, In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2
The paper presents experimental data regarding a number of seven new benzimidazo[2,3-d]thiazolo[4,5-b] quinoxaline dyes have been synthesized by condensation of 2,3-dichloroquinoxaline with different 1,3-dihydro-2H- benzimidazole-2-thione derivatives. Reaction products were purified and characterized by means of elemental analysis, UV-VIS, IR, 1H and 13C-NMR, mass spectra and thermal analysis. Structure-property relationships in the dyes are discussed with respect to the nature of the substituents in the benzimidazole moieties.
