Description
Guaiacol is a naturally-occurring organic compound with the formula C6H4(OH)(OCH3), first isolated by Otto Unverdorben in 1826. Although it is biosynthesized by a variety of organisms, this yellowish aromatic oil is usually derived from guaiacum or wood creosote. Samples darken upon exposure to air and light. Guaiacol is present in wood smoke, resulting from the pyrolysis of lignin. The compound contributes to the flavor of many substances such as whisky and roasted coffee.
Application
Guaiacol is used for cough with phlegm in chronic tracheitis, and is often used together with other antiasthmatic drugs. Guaiacol is a natural organic substance with a special fragrance.Guaiacol is widely used in daily life. It can be used as an edible spice in cigarettes, in the production of vanilla, and in the preparation of coffee.Clinically, it can be made into compound preparations, tablets and syrups, such as compound guaiacol sulfonate oral liquid and medical guaiacol glycerol ether
Laboratory methods
Guaiacol can be prepared by diverse routes in the laboratory. o-Anisidine, derived in two steps from anisole, can be hydrolyzed via its diazonium derivative. Guaiacol can be synthesized by the dimethylation of catechol followed by selective mono-demethylation
Uses and chemical reactions
Guaiacol is a precursor to various flavorants, such as eugenol[10] and vanillin.[11] An estimated 85% of the world's supply of vanillin comes from guaiacol. The route entails condensation of glyoxylic acid with guaiacol to give mandelic acid, which is oxidized to produce a phenylglyoxylic acid. This acid undergoes a decarboxylation to afford vanillin.
As a pheromone
Guaiacol is produced in the gut of desert locusts, Schistocerca gregaria, by the breakdown of plant material. This process is undertaken by the gut bacterium Pantoea agglomeransa (Enterobacter). It is one of the main components of the pheromones that cause locust swarming.
Safety
Methoxyphenols are potential biomarkers of biomass smoke exposure, such as from inhalation of woodsmoke. Dietary sources of methoxyphenols overwhelm the contribution from inhalational exposures to woodsmoke.
