Used in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of alkaloid-based drugs. Serves as an intermediate in the preparation of nitrogen-containing heterocyclic compounds with potential antimicrobial, antitumor, and anti-inflammatory properties. Employed in research for the construction of complex natural products and in medicinal chemistry for designing enzyme inhibitors. Also utilized in the formation of fluorescent probes and dyes due to its aromatic structure and reactivity in condensation reactions.
