Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients in crop protection agents and medicinal compounds. Its aldehyde functional group allows for easy modification, making it valuable in building complex heterocyclic systems. Commonly employed in research settings for creating pyrazole-based derivatives with potential biological activity, including anti-inflammatory, antimicrobial, and kinase inhibitory properties. Also utilized in the preparation of dyes and functional materials due to its aromatic and reactive nature.
