Used in the synthesis of pharmaceutical intermediates, particularly in the development of anti-inflammatory and analgesic drugs. It serves as a building block in organic synthesis due to the presence of both hydroxyl and amide functional groups, allowing for selective modifications. Also employed in the preparation of agrochemicals and dyes, where chloro-substituted aromatic compounds enhance stability and reactivity. Its hydroxy and amide moieties enable hydrogen bonding, useful in crystal engineering and designing supramolecular structures.
