Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals. It serves as a building block for pyrazolone-based drugs, which exhibit analgesic, anti-inflammatory, and antipyretic properties. Commonly found in research related to non-steroidal anti-inflammatory agents (NSAIDs). Also utilized in the preparation of dyes and fragrances due to its aromatic and structural characteristics. Shows potential in coordination chemistry as a ligand for metal ions in catalytic applications.
