Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and anti-inflammatory agents. It serves as a building block in the preparation of pyrazole-based compounds with biological activity, including potential anticancer and antimicrobial drugs. Its aldehyde functional group allows for easy modification through condensation or reduction reactions, enabling the creation of diverse derivatives for structure-activity relationship studies in medicinal chemistry. Also employed in agrochemical research for designing new crop protection agents.
