Used in the synthesis of pharmaceuticals and fine chemicals, particularly as an intermediate in the production of nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a building block in organic synthesis due to its reactive carbonyl and carboxylic acid functional groups, enabling esterification, reduction, and condensation reactions. Also employed in the development of photoinitiators for UV-curable coatings and resins, where it contributes to efficient radical generation upon light exposure. Its aromatic ketone structure makes it useful in designing compounds for specialty polymers and agrochemicals.
