Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihistamines, anti-inflammatory drugs like ketoprofen, and benzodiazepines such as triazolam. It also serves as a building block in the manufacture of UV absorbers and photoinitiators for polymers, enhancing material stability under sunlight. Additionally, it finds use in the development of agrochemicals, antifungals, insecticides, and certain dyes due to its aromatic ketone structure, which supports complex organic transformations including chloride substitution and ring modifications.
