Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its fluorinated benzofuran core enhances metabolic stability and binding affinity in drug candidates. Also employed in the preparation of bioactive molecules for research in neuropharmacology and medicinal chemistry. The carboxylic acid functionality allows for easy derivatization, enabling the formation of amides, esters, and other functional groups important in drug design.
