Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates targeting central nervous system disorders. Its aldehyde functional group allows for easy modification and incorporation into more complex structures, making it valuable in medicinal chemistry for building heterocyclic compounds. Commonly employed in reductive amination and condensation reactions to create amine derivatives with potential therapeutic activity. Also utilized in the preparation of kinase inhibitors and receptor modulators due to its favorable ring structure and nitrogen positioning.
