Molecular structure
guaiacol
Cooking relevance
Guaiacol (2-methoxyphenol, PubChem CID 460) is a phenolic compound that imparts distinctive smoky, warm character to foods. It forms naturally during smoking and wood-aging processes, and appears in smoked meats, whiskeys, and aged spirits. Its presence defines the sensory profile of smoke-treated ingredients and contributes to complex savory depth in cured and barbecued preparations.

1-(4-hydroxy-3-methoxyphenyl)-2-(2-methoxyphenoxy)propane-1,3-diol + H2O2 = guaiacol + vanillin + glycolaldehyde + H2O
1-(3,4-dimethoxyphenyl)-2-(2-methoxyphenoxy)propane-1,3-diol + H2O2 = 3,4-dimethoxybenzaldehyde + guaiacol + glycolaldehyde + H2O
vanillate + H(+) = guaiacol + CO2
guaiacol + reduced [NADH--hemoprotein reductase] + O2 = oxidized [NADH--hemoprotein reductase] + catechol + formaldehyde + H2O + H(+)
