2,4,6-tribromanisole is an aromatic compound . The structure consists of a benzene ring with an attached methoxy group  (–OCH 3 ) and three bromine atoms  (–Br) as substituents .

Occurrence

2,4,6-tribromanisole was identified in 2004 by Pascal Chatonnet as a musty odor component of some wines . The connection has also been detected in fish and marine sediments.

Extraction and presentation

2,4,6-Tribromanisole can be obtained by O -methylation of its direct precursor 2,4,6-tribromophenol . Since it also occurs as a metabolite of the compound used as a fungicide , it is held responsible for odor defects in food.

properties

2,4,6-Tribromanisole is a colorless solid with a musty odor that is practically insoluble in water. It can be perceived even in very low concentrations.

use

2,4,6-Tribromanisole is used in the manufacture of dyes, flame retardants and brominated aromatic compounds.
