Used as an intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of indole-based drugs. Its structure supports the construction of complex heterocyclic systems found in medicinal chemistry. Commonly employed in research settings for creating analogs with potential anti-inflammatory, anticancer, or neurological activity. Also utilized in agrochemical research for designing new active ingredients. Its aldehyde and ester functional groups allow for diverse chemical modifications, making it valuable in combinatorial chemistry and drug discovery.
