Employ:
Allowed edible perfume. Natural Guaiacol is used in confect a series of essence of coffee, herb, fumes and tobacco. Natural Guaiacol is also use as perfume and antioxidants in food and daily chemicals synthesize vanillin and pharmaceutical intermediates. General Description Colorless to amber crystals or liquid. Dichte (of solid) 1.129 g / cm3. Solidifies at 28°C (82.4°F), but may remain liquid for a long time even at a much lower temperature. Slightly water soluble. Soluble in aqueous sodium hydroxide. Used medicinally as an expectorant. Used, because of its anti-oxidant properties, as an anti-skinning agent for paints. Air & Water Reactions Sensitive to air and light (darkens). Slightly water soluble.
Reactivity Profile: 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.
Safety:
Methoxyphenols are potential biomarkers of biomass smoke exposure, Testosteronpropionat im mittleren Körper, from inhalation of woodsmoke. Dietary sources of methoxyphenols overwhelm the contribution from inhalational exposures to woodsmoke.
Locust 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.
