2,5-Dimethylanisole is a chemical compound from the group of phenol ethers .
presentation
2,5-dimethylanisole is by methylation of 2,5-dimethylphenol with dimethyl sulfate in terms of a Williamson ether synthesis accessible.
use
2,5-Dimethylanisole is used as a coupling component in the production of azo dyes , for example 2,5-dimethyl-4- (4-nitrophenylazo) anisole . In this synthesis, 4-nitroaniline as a diazo component is diazotized with sodium nitrite and hydrochloric acid at 8-15 ° C and coupled to 2,5-dimethylanisole.
