3,5-Dimethoxytoluene Usage And Synthesis

Chemical Properties

Clear colorless to yellow liquid

Uses

3,5-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).

Definition

ChEBI: 3,5-dimethoxytoluene is a member of the class of toluenes that is toluene in which the hydrogens at positions 3 and 5 have been replaced by methoxy groups. It is the major scent compound of many rose varieties. It has a role as a fragrance and a plant metabolite. It is a member of toluenes and a member of methoxybenzenes.

General Description

3,5-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.
