It is slightly soluble in water and benzene, also easily soluble in glycerol. And it is miscible with ethanol, ether, chloroform, oil and glacier acetic acid. Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. It is also present in wood smoke, as a product of pyrolysis of lignin.
ChEBI: Guaiacol is a monomethoxybenzene that consists of phenol with a methoxy substituent at the ortho position. It has a role as an expectorant, a disinfectant, a plant metabolite and an EC 1.1.1.25 (shikimate dehydrogenase) inhibitor. It is functionally related to a catechol.
Guaiacol is a colorless to amber crystals or liquid. Density (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. It is an agent thought to have disinfectant properties and used as an expectorant.
