4hydroxy3methoxyphenol

4hydroxy3methoxyphenol, also known as vanillyl alcohol, is an organic compound with the chemical formula C8H10O3. It is a phenolic compound and a derivative of guaiacol. Vanillyl alcohol is structurally related to vanillin, the primary component of vanilla bean extract, differing by the presence of a hydroxyl group instead of an aldehyde group. It appears as a white to off-white crystalline solid.

Vanillyl alcohol can be found naturally in certain plants, though often in trace amounts. It can be synthesized through various chemical routes, commonly involving the reduction of vanillin. Its chemical properties include its solubility in water and organic solvents, and its reactivity typical of phenols.

The compound has found some applications in research and industry. It has been investigated for its antioxidant properties, similar to other phenolic compounds. In some instances, it has been used as a precursor or intermediate in the synthesis of other chemicals, including pharmaceuticals and flavorings. Its role in biological systems is still an area of ongoing scientific study. It is not typically used as a food additive or flavoring agent directly.
