Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with anti-inflammatory and analgesic properties. Its aldehyde functional group allows for easy modification, enabling the formation of Schiff bases or further carbon chain extensions, which are valuable in drug design. Commonly employed in heterocyclic chemistry to build complex pyrazole derivatives that exhibit biological activity. Also utilized in agrochemical research for developing new crop protection agents due to its stable aromatic and heterocyclic framework.
