Description

Quindoxin, also known as grofas or quindoxin hydride, belongs to the class of organic compounds known as quinoxalines. Quinoxalines are compounds containing a quinoxaline moiety, a bicyclic heterocycle made up of a benzene ring fused to a pyrazine ring. Based on a literature review very few articles have been published on Quindoxin.
