Used in the synthesis of pharmaceuticals, particularly as an intermediate in developing drugs with anti-inflammatory and analgesic properties. It also serves as a building block in the preparation of fluorescent dyes and sensors due to its ability to form conjugated systems that enhance optical properties. Its structure supports metal coordination, making it useful in catalysis and in the design of bioactive molecules targeting neurological disorders. Additionally, it finds application in agrochemicals for developing herbicides and plant growth regulators.
