Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active compounds. Its structure supports the construction of fluorinated indole derivatives, which are valuable in medicinal chemistry for enhancing metabolic stability and bioavailability. Commonly employed in research settings to design novel drug candidates targeting neurological disorders, including depression, anxiety, and migraine. Also utilized in the preparation of fluorescent probes and labeled compounds for biochemical assays due to the favorable electronic properties introduced by the fluorine atom.
