Isoalloxazine is the structural foundation of flavins such as riboflavin (vitamin B2) and is a heterocyclic compound.[2] It has a tricyclic structure which means it has three interconnected rings of atoms and is a tautomer of alloxazine.[1] The structure is formed by primary-secondary aromatic o-diamines and they are a high-melting crystalline substance.[1] The R-group is used to attach various flavin groups It has a similar structure to pteridines which has two interconnected rings.[1] Isoalloxazine was first obtained in 1934[1] by Richard Kuhn an Austrian-German biochemist and lab mates.
