2,4-Quinolinediol Chemical Properties,Uses,Production
Chemical Properties
very light brown powder
Uses
2,4-Quinolinediol is a coupling component of yellow azo dyes, also used as pharmaceutical intermediates.
Application
Researchers have found that the hetarylazoquinoline dyes were prepared by coupling 2,4-quinolinediol with diazotised heterocyclic amines in nitrosylsulphuric acid. In addition, the crude enzyme preparation effectively promotes the reaction between 4-hydroxy-1-methyl-2-quinolinone and 2,4-quinolinediol to afford the corresponding benzofuroquinolinones in satisfactory yields[1-2].
Definition
ChEBI: A heteroaryl hydroxy compound that is 2-quinolone substituted at position 4 by a hydroxy group.
