Description

General description

2,5-Dimethoxytoluene (1,4-dimethoxy-2-methyl benzene) is a methoxy methyl benzene derivative. It has been synthesized from 2-methylhydroquinone. It is one of the volatile constituents identified from beechwood creosote and Tuber brumale species. It is reported to be one of the thermochemolysis products in Delaware bay particles and dissolved organic matters.

Application

2,5-Dimethoxytoluene may be used as a reagent in the synthesis of 2,5-dimethoxy-4-methylbenzaldehyde-7-¹⁴C. Its IR spectrum has been used to establish the methyl group migration in the acid catalyzed rearrangement of 4-methoxy-4-methylcyclohexadienone.
