In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen. This alkoxy group has the formula R−O−CH 3 . On a benzene ring , the Hammett equation classifies a methoxy substituent at the para position as an electron-donating group , but as an electron-withdrawing group if at the meta position.
In chemistry, the alkoxy group is an alkyl group which is singularly bonded to oxygen; thus R−O. Denoted usually with apostrophe('). The range of alkoxy groups is vast, the simplest being methoxy (CH 3 O−). [1] An ethoxy group (CH 3 CH 2 O−) is found in the organic compound ethyl phenyl ether (C 6 H 5 OCH 2 CH 3, also known as ethoxybenzene).
It is a phenolic compound containing a methoxy functional group. Guaiacol appears as a viscous colorless oil, although aged or impure samples are often yellowish. It occurs widely in nature and is a common product of the pyrolysis of wood. [3]
Directed ortho metalation (DoM) is an adaptation of electrophilic aromatic substitution in which electrophiles attach themselves exclusively to the ortho-position of a direct metalation group or DMG through the intermediary of an aryllithium compound. [1] The DMG interacts with lithium through a hetero atom.
14-Methoxymetopon is an experimental opioid drug developed by a team led by Professor Helmut Schmidhammer at the University of Innsbruck in the mid-1990s. [1] It is a derivative of metopon in which a methoxy group has been inserted at the 14-position.

Radwah Oda was diagnosed with colon cancer at 30. She shares five symptoms she dismissed, including narrow stools, blood in the stool, pain and fatigue.
Methoxyacrylates hold significant importance in the field of agricultural fungicides, with a substantial market share. In 1999, this group of active ingredients accounted for over 10% of the fungicide market, with sales totaling US$620 million, led by azoxystrobin, which alone generated approximately US$415 million in sales.
