Definition

ChEBI: 5,7-dibromo-8-quinolinol is a member of quinolines and an organohalogen compound.

Manufacturing Process

To a suspension of 14.5 g of 8-hydroxyquinoline in 400 ml of water was added dropwise a solution of 32.3 g bromine and 30 g 8% aqueous hydrobromide in 30 ml water. A temperature of reaction mixture decreased to 33°C. Stirring was continued for 30 min, a fine yellow 5,7-dibromo-8-hydroxyquinoline was collected by filtration, washed with water and dried; yield 29.8 g (98.4%), melting point 201°C.
