1,2-Dimethoxybenzene Usage And Synthesis
  • Description1, 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, too.
    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.
  • Uses1, 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.

  • Chemical PropertiesColorless crystals or liquid. Soluble in alcohol and ether; slightly soluble in water.
  • OccurrenceReported present in asparagus (raw and cooked), bonito (dried), broccoli (cooked), cauliflower (cooked), cognac, endive, grape, Gruyere de Comte cheese, guava, leek (raw and heated), olive, peas, rhubarb, rice bran and vanilla extract.
  • PreparationPrepared by methylation of pyrocatechol.
  • DefinitionChEBI: A dimethoxybenzene with the methoxy groups at ortho-positions.
  • Taste threshold valuesIntolerable at 40 ppm.
  • Purification MethodsSteam distil veratrole, then fractionally distil it from BaO, CaH2 or Na. Crystallise it from *benzene or low-boiling pet ether at 0o. Fractionally crystallise it from its melt. Store it over anhydrous Na2SO4. [Beilstein 6 IV 5564.]
