Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and anticancer agents. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems. Commonly employed in medicinal chemistry for building blocks in drug discovery programs targeting tyrosine kinases and other signaling proteins. Also utilized in agrochemical research for designing bioactive molecules with pesticidal or herbicidal activity. Its aldehyde group enables easy derivatization via reductive amination or condensation reactions, facilitating rapid generation of compound libraries for screening.
