99.8% Purity Pharmaceutical Raw Materials Guaiacol as Steroids Solvent
Description:
Guaiacol is a phenolic compound with a methoxy group and is the monomethyl ether of catechol. Guaiacol is readily oxidized by the heme iron of peroxidases including the peroxidase of cyclooxygenase (COX) enzymes. It therefore serves as a reducing co-substrate for COX reactions. Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. It is a yellowish aromatic oil that is now commonly derived from guaiacum or wood creosote. It is used medicinally as an expectorant, antiseptic, and local anesthetic. Guaiacol is used in traditional dental pulp sedation, and has the property of inducing cell proliferation; guaiacol is a potent scavenger of reactive oxygen radicals and its radical scavenging activity may be associated with its effect on cell proliferation. Guaiacol is also used in the preparation of synthetic vanillin. Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. Guaiacol has been found in the urine of patients with neuroblastoma and pheochromocytoma.

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.
Benefits:
We monitor your health and alert you to any safety updates and recalls.
You get to talk directly to other members about their experience.
You can create profiles for you and your loved ones.
Safety:
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.
