Description and Uses

P-Anisic acid, also known as 4-Methoxybenzoic acid or draconic acid, is an organic acid that has a sweet flavor. It is one of the isomers of anisic acid, including m-anisic acid and o-anisic acid. The term "anisic acid" often refers to this form specifically. P-anisic acid is produced through the oxidation of p-cresyl-methyl ether.

4-Methoxybenzoic acid (p-Anisic acid) is used in oxidation and reduction of cytochrome c in solution through different self-assembled monolayers on gold electrodes using cyclic voltammetry. p-Anisic acid has antiseptic properties. It is also used as an intermediate in the preparation of more complex organic compounds.
