Molecule of the Week


June 20, 2011

Guaiacol, or o-methoxyphenol, was first isolated from the tree resin guaiac by A. Sobrero in 1843. Today, it is manufactured by methylating catechol (o-dihydroxybenzene). It is used medically as an expectorant, antiseptic, and local anesthetic; it is also a precursor to flavorants and aromas, including those incorporated in synthetic sandalwood.
