Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine heterocycles and their benzo derivatives possess many interesting properties, including chemical reactivity profiles, and have diverse applications in total synthesis, medicine, chemical biology, materials, dyes, and imaging.

Electron affinities of aza-substituted polycyclic aromatic hydrocarbons was written by Dillow, Glen W.;Kebarle, P.. And the article was included in Canadian Journal of Chemistry in 1989.Reference of 322-46-3 This article mentions the following:

Electron affinities (EA) for aza-substituted polycyclic aromatics, e.g., quinazoline, were determined from measurements of electron transfer equilibrium in the dilute gas phase with a pulsed electron high pressure mass spectrometer. Solvation energies of the corresponding radical anions in acetonitrile and DMF are derived from the gas-phase data and literature on electron reduction potentials in solution An observed linear relation between the electron affinities and the reduction potentials allows estimates of electron affinities to be made for 12 aza compounds whose EA’s are too low to be measured with the present method. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3Reference of 322-46-3).
