Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and selective COX-2 inhibitors. It serves as a building block in agrochemicals for creating herbicides and fungicides due to its stable heterocyclic structure. Also employed in the preparation of dyes and fluorescent probes for biochemical labeling. Its amine functionality allows easy modification for use in combinatorial chemistry and drug discovery research.
