Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory, analgesic, and antipyretic drugs. It serves as a building block in heterocyclic chemistry, enabling the construction of complex pyrazole derivatives with biological activity. Also applied in agrochemicals for the design of herbicides and pesticides due to its ability to modulate enzyme activity in target organisms. Additionally, it finds use in materials science for the development of fluorescent dyes and sensors, leveraging its electron-donating properties and structural stability.
