Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure supports the creation of bioactive molecules due to the presence of reactive aldehyde group and fused heterocyclic ring, enabling functionalization for drug design. Commonly employed in medicinal chemistry for constructing pyridine-based derivatives with potential cognitive and neuroprotective effects. Also utilized in research settings for generating compound libraries in search of new therapeutic agents.
