2,6-Dimethoxyphenol Usage And Synthesis
Chemical Properties2,6-Dimethoxyphenol is an off-white or grey to brown crystalline powder that has a woody, medicinal, rather dry odor.
OccurrenceReported found in beechwood tar creosote, onion, garlic, leek, chive, nira (Allium tuberosum Rotti), nobira (Allium grayi Regal) and caucus (Allium victoralis L.)
Uses2,6-Dimethoxyphenol has been used as a metabolite of lignin depolymerisation.It is also used as flavoring agent or adjuvant.It is reported to be the single most important flavor chemical in smoke flavors. It is used in smoke flavors, whisky, rum, tea, spice, savory, seafood, meat, liquorices, coffee, and nut flavors.
Preparation2,6-Dimethoxyphenol is prepared by reacting pyrogallol with methyl iodide in alkaline aqueous medium; by demethylation of pyrogallol trimethyl ether in aqueous alkali or in alcohol.
DefinitionChEBI: 2,6-dimethoxyphenol is a member of the class of phenols that is phenol substituted by methoxy groups at positions 2 and 6. It has a role as a plant metabolite. It is a member of phenols and a dimethoxybenzene.
Aroma threshold valuesDetection: 400 ppb to 1.85 ppm
Taste threshold valuesTaste characteristics at 60 ppm: sweet, medicinal, creamy, meaty, vanilla, spice.
