3,5-Dimethoxytoluene Usage And Synthesis
Chemical PropertiesClear colorless to yellow liquid
Uses3,5-Dimethoxytoluene (DMT) may be used in the synthesis of 3,5-dimethoxybenzoic acid by oxidation and 2-methoxy-6-methyl-1,4-benzoquinone by catalytic oxidation with hydrogen peroxide (H2O2)/methyltrioxorhenium (CH3ReO3) in dimethyl carbonate (DMC).

General Description3,5-Dimethoxytoluene (DMT) is a methoxylated phenolic derivative. It is reported to be one of the main constituent of the floral volatiles in different rose varieties. It has been biosynthesized from orcinol by two successive methylation catalyzed by O-methyltransferases (OMTs). The features of its aerobic oxidation with metal/bromide catalysts have been investigated.
