Occurrence

1,2-Dimethoxybenzene is naturally occurring. Its biosynthesis entails the methylation of guaiacol by guaiacol O-methyltransferase.[3] 1,2-Dimethoxybenzene is an insect attractant.[3] Guaiacol O-methyltransferase gene is first scent gene discovered so far in any plant species.[3]

Uses

1,2-Dimethoxybenzene is a building block for the organic synthesis of other aromatic compounds. Veratrole is relatively electron-rich and thus readily undergoes electrophilic substitution.[4]

An example of the use of veratrole is in the synthesis of Domipizone.[5]

Veratrole can easily be brominated with NBS to give 4-bromoveratrole.[6]
