Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrazole-based drugs with anti-inflammatory, antimicrobial, and anticancer properties. Its aldehyde functional group allows for easy modification, enabling the formation of Schiff bases and other derivatives important in medicinal chemistry. Also employed in agrochemical research for designing novel pesticides and herbicides due to its stable aromatic structure and reactivity. Commonly utilized in organic synthesis for constructing complex heterocyclic systems in drug discovery programs.
