| | 2,4-Quinolinediol Usage And Synthesis |
| 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].
