Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrazole-based drugs with anti-inflammatory, analgesic, and antimicrobial properties. It serves as a building block in agrochemicals for creating herbicides and pesticides due to its reactive aldehyde group that allows functionalization. Also employed in the preparation of dyes and functional materials where heterocyclic frameworks enhance electronic or optical properties. Its versatility in cross-coupling and condensation reactions makes it valuable in medicinal chemistry research and development.
