1,2-Dimethoxybenzene, commonly known as veratrole, is an organic compound with the formula C6H4(OCH3)2. It is a colorless liquid, with a pleasant odor and slight solubility in water. It is the dimethyl ether derived from pyrocatechol.

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

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.

An example of the use of veratrole is in the synthesis of Domipizone.

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