Metahydroxybenzoate

Metahydroxybenzoate refers to a class of chemical compounds that are derivatives of benzoic acid, characterized by a hydroxyl group (-OH) attached to the meta position (the third carbon atom) of the benzene ring. The general formula for metahydroxybenzoate is C7H6O3, although specific compounds will vary based on the associated cation or further substitutions. The parent compound is 3-hydroxybenzoic acid, also known as m-hydroxybenzoic acid.

These compounds are organic acids and can participate in typical reactions of carboxylic acids and phenols. They are often found as esters or salts. For example, methyl metahydroxybenzoate is the methyl ester of 3-hydroxybenzoic acid. The properties of metahydroxybenzoates, such as their solubility, melting point, and reactivity, are influenced by the presence of both the carboxyl group and the hydroxyl group on the aromatic ring.

Metahydroxybenzoic acid itself can be found naturally in some plants and is a known metabolite in certain biological processes. Derivatives of metahydroxybenzoates have been explored for various applications, including as preservatives, pharmaceuticals, and in the synthesis of other organic molecules. Their potential biological activities are a subject of ongoing research.
