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.
