Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of serotonin receptor modulators and anti-inflammatory agents. Its structure supports the creation of bioactive molecules due to the presence of both indole and fluorophenyl groups, which are common in central nervous system drugs. Also employed in the preparation of fluorescent probes and dyes owing to its aldehyde functionality and conjugated aromatic system. Shows potential in medicinal chemistry for designing compounds with enhanced metabolic stability and binding affinity.
