2,4-Quinolinediol Chemical Properties,Usage,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.
