ohydroxyanisole

o-hydroxyanisole, also known as o-hydroxyanisole or 2-hydroxyanisole, is an organic compound in the class of phenols and methoxybenzenes. Its systematic name is 2-methoxyphenol, reflecting a methoxy group attached to the benzene ring adjacent to a hydroxyl group. The chemical formula is C7H8O2, and it is commonly referred to by the trivial name guaiacol.

Natural occurrence and production methods are linked to its presence in wood smoke and certain essential oils. Guaiacol is also produced commercially as an intermediate in the synthesis of flavors, fragrances, and other phenolic compounds. It has historically been associated with the guaiac resin family and can be derived or formed in industrial processes that construct methoxyphenol structures.

Applications of o-hydroxyanisole center on flavor, fragrance, and chemical synthesis. It contributes a smoky, characteristic odor and is used as a fragrance ingredient in some products. Chemically, it serves as an important intermediate in the production of vanillin and related phenolic compounds, and it may be employed in the manufacture of various fragrances and flavor formulations.

Safety and handling considerations are important when working with phenolic compounds. o-hydroxyanisole can be irritant to skin, eyes, and the respiratory tract; ingestion or improper exposure may be harmful. It is also flammable and should be handled with appropriate ventilation, personal protective equipment, and storage away from sources of ignition.
