Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive compounds. Its structure allows for functionalization at multiple sites, making it valuable in constructing complex molecules. Commonly employed in the development of drug candidates targeting central nervous system disorders due to the presence of dimethoxyphenyl moiety, which is often associated with neuroactive properties. Also utilized in the synthesis of fragrances and specialty esters owing to its carboxylic acid group and aromatic features.
