Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 inhibitors. It serves as a building block in agrochemicals for creating herbicides and pesticides due to its stable heterocyclic structure. Also employed in research for designing novel bioactive molecules and in the preparation of pyrazole-based dyes and fluorescent probes for biochemical imaging.
