Used as a key intermediate in pharmaceutical synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl structures. Its indole core with boronate ester functionality enables efficient formation of carbon-carbon bonds, making it valuable in developing drug candidates targeting neurological disorders, inflammation, and cancer. The fluorine substituent enhances binding selectivity and metabolic stability in final active compounds. Commonly employed in research settings for lead optimization in medicinal chemistry programs.
