Used primarily as a key intermediate in pharmaceutical synthesis, especially in Suzuki-Miyaura cross-coupling reactions to construct biaryl frameworks. Its indole core with a boronate ester group enables selective carbon-carbon bond formation, making it valuable in the development of bioactive molecules and drug candidates targeting neurological disorders, inflammation, and cancer. The fluorine substituent enhances binding affinity and metabolic stability in final active compounds, improving their pharmacokinetic profile. Commonly employed in research laboratories and early-stage drug discovery for generating novel indole derivatives with tailored biological activities.
