Reaktivitätsprofil: Guaiacol may react with oxidizing materials. Guaiacol forms salts readily with bases.
Fire Hazard Guaiacol is combustible.
Uses and chemical reactions:
Guaiacol is a precursor to various flavorants, such as eugenol and vanillin.An estimated 85% of the worlds 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.
Sicherheit:
Methoxyphenole sind potenzielle Biomarker für die Exposition gegenüber Biomasserauch, Testosteronpropionat im mittleren Körper, durch Einatmen von Holzrauch. Nahrungsquellen für Methoxyphenole überwiegen den Beitrag der inhalativen Exposition gegenüber Holzrauch.
Heuschreckenpheromon:
Guajakol wird im Darm von Wüstenheuschrecken produziert, Schistocerca gregaria, durch den Abbau von Pflanzenmaterial. Dieser Prozess wird vom Darmbakterium Pantoea agglomeransa durchgeführt (Enterobacter). Es ist einer der Hauptbestandteile der Pheromone, die Heuschreckenschwärme verursachen.
