Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a building block in organic synthesis due to the presence of both hydroxyl and carboxylic acid functional groups, which allow for further chemical modifications. Also employed in the development of agrochemicals and dyes, where chloro-hydroxy aromatic structures are required. Its reactivity makes it valuable in coupling reactions and heterocycle formation.
