Used in organic synthesis as a building block for pharmaceuticals and biologically active compounds. Serves as a precursor in the preparation of indole-based derivatives, which are important in drug development, particularly for central nervous system agents and anti-inflammatory drugs. Also utilized in coordination chemistry as a ligand for metal ions, enabling the design of metal-organic frameworks (MOFs) with potential applications in catalysis and sensing. Its rigid structure and functional groups make it suitable for constructing complex heterocyclic systems in medicinal chemistry research.
