2-Quinoxalinone Usage And Synthesis

Chemical Properties

White to yellow to light brown solid

Uses

2-Quinoxalinone is a metabolite of Quinalphos, and is known to photocatalytically destroy antioxidant vitamins and biogenic amines in vitro and is genotoxic to both light- and dark-exposed bacteria.

Definition

ChEBI: A hydroxyquinoxaline that consists of quinoxaline having a single hydroxy substituent located at position 2.

General Description

Epitaxial crystallization of syndiotactic polypropylene on 2-quinoxalinol yields isochiral form II of syndiotactic polypropylene. 2-Quinoxalinol participates in direct dehydrative cross-coupling of 2-quinoxalinone with p-tolylacetylene via Pd/Cu-catalyzed phosphonium coupling.
