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. |
