Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure supports the creation of bioactive molecules due to the presence of both carboxylic acid and phenolic hydroxyl groups, enabling diverse chemical modifications. Commonly employed in research settings for designing analogs of neuroactive drugs, including those with sedative, anxiolytic, or anticonvulsant properties. Also utilized in the preparation of prodrugs where controlled release is required through esterification or conjugation at the acid or hydroxyl sites.
