描述

一般說明

2,5-Dimethoxytoluene (1,4-dimethoxy-2-methyl benzene) is a methoxy methyl benzene derivative.[1] It has been synthesized from 2-methylhydroquinone.[2] It is one of the volatile constituents identified from beechwood creosote[3] and Tuber brumale species.[1] It is reported to be one of the thermochemolysis products in Delaware bay particles and dissolved organic matters.[4]

應用

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