Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients for crop protection products. Its structure allows for functionalization in heterocyclic compound design, making it valuable in medicinal chemistry for building bioactive molecules. It is also employed in the preparation of pyrazole-based derivatives with potential antimicrobial, anti-inflammatory, or insecticidal properties. Its aldehyde group enables easy modification through condensation or reduction reactions, facilitating its use in multi-step organic syntheses.
