A 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. They are isomeric with quinazolines.
Additional recommended knowledge
They are formed by the condensing ortho-diamines with 1,2-diketone; the parent substance of the group, quinoxaline, resulting when glyoxal is so condensed, whilst substitution derivatives arise when α-ketonic acids, α-chlorketones, α-aldehyde alcohols and α-ketone alcohols are used in place of diketones.
