3,4-Dibromophenol is a chemical compound that belongs to both phenols and halogen aromatic compounds .

presentation

The synthesis of 3,4-dibromophenol starts from 3,4-dibromonitrobenzene , which is reduced with iron in ethanol to 3,4-dibromaniline . This is then converted to the desired compound by boiling the diazonium compound formed with sodium nitrite .

Manufacture of 3,4-dibromophenol

Derivatives

The methyl ether can be produced by methylation with dimethyl sulfate and is also known under the common name 3,4-dibromanisole (CAS number: 62415-74-1).
