Oil Based Steroids Guaiacol CAS: 90-05-1 Light Yellow Liquild Powerful Hormone Solvent
Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. Guaiacol is readily oxidized by the heme iron of peroxidases including the peroxidase of cyclooxygenase (COX) enzymes. It therefore serve as a reducing co-substrate for COX reactions.1 The color yield per peroxide at 470 nm is 6,650 (M peroxide reduced)-1 cm-1.2,3,4 Two moles of guaiacol are oxidized for each mole of hydroperoxide reduced by the peroxidase. The resulting guaiacol chromophore can be used for the colorimetric determination of hydroperoxidase activity.

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.
Methoxyphenols are potential biomarkers of biomass smoke exposure, e.g., from inhalation of woodsmoke. Dietary sources of methoxyphenols overwhelm the contribution from inhalational exposures to woodsmoke.
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.
