1,2-Dimethoxybenzene, commonly known as veratrole, is an organic compound with the formula C6H4(OCH3)2. It is one of three isomers of dimethoxybenzene. It is a colorless liquid, with a pleasant odor and slight solubility in water. It is the dimethyl ether derived from pyrocatechol.
Occurrence
1,2-Dimethoxybenzene is naturally occurring. Its biosynthesis entails the methylation of guaiacol by guaiacol O-methyltransferase. 10.1186/1471-2229-12-158 22937972 3492160 Identification of white campion (Silene latifolia) guaiacol O-methyltransferase involved in the biosynthesis of veratrole, a key volatile for pollinator attraction BMC Plant Biology 12 158 2012 Gupta Alok K Akhtar Tariq A Widmer Alex Pichersky Eran Schiestl Florian P free 1,2-Dimethoxybenzene is an insect attractant. Guaiacol O-methyltransferase gene is first scent gene discovered so far in any plant species.
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-Iodoveratrole Janssen, D. E. Wilson, C. V. 4 547 1963 CV4P0547
