Quinoxaline, also called a benzopyrazine, in organic chemistry, is a heterocyclic compound containing a ring complex made up of a benzene ring and a pyrazine ring.
Interesting scientific research on 2,3-Dichloroquinoxaline
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 2213-63-0, and how the biochemistry of the body works.Application of 2213-63-0
New Advances in Chemical Research, May 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates. Application of 2213-63-0, We’ll be discussing some of the latest developments in chemical about CAS: 2213-63-0, name is 2,3-Dichloroquinoxaline. In an article，Which mentioned a new discovery about 2213-63-0
The standard (po = 0.1 MPa) molar enthalpies of formation for liquid 2-chloropyrazine and crystalline 2,6-dichloropyrazine, 2,3-dichloroquinoxaline and 2,3,6,7-tetrachloroquinoxaline were derived from the standard molar enthalpies of combustion, in oxygen, to yield CO2(g), N2(g), and HCl * 600H2O(l), at the temperature T = 298.15 K, measured by rotating-bomb combustion calorimetry. The standard molar enthalpies of vaporization or of sublimation, at T = 298.15 K, were measured by Calvet microcalorimetry.
Density functional theory with the B3LYP functional and two different basis sets, 6-31G* and 6-311G**, was used to optimize the geometries of all chloro-substituted pyrazines and some chloro-substituted quinoxalines. The calculation of the energy of isodesmic reactions allowed the estimation of the standard molar enthalpies of formation in the gas phase for all compounds including some not studied experimentally.
