Chemical Structure

Basic Info
Guaiacol is an organic compound with the chemical formula C7H8O2, belonging to the phenolic compounds. It is synthesized from guaiac oil or other aromatic compounds through catalytic reactions and has a special aroma and taste. The molecular structure of guaiacol contains a phenolic group (-OH) and a methoxyl group (-OCH3), which makes it highly chemically active. It is often used as an intermediate for solvents, fragrances, and drugs, and it is also widely used in the chemical industry, such as in synthetic drugs and organic synthesis reactions.
In cosmetics, guaiacol is a fragrance ingredient in skin care products, especially in skin creams, shampoos and other products, providing a mild aroma and a certain antioxidant effect. In addition, guaiacol has also been studied as a compound with potential biological activities, such as anti-inflammatory and antibacterial, and has certain market application prospects.
