Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for active pharmaceutical ingredients due to its aromatic and carboxylic functional groups, which allow for further chemical modifications. Also employed in the development of agrochemicals, including certain herbicides and plant growth regulators, where the dichlorophenyl moiety contributes to bioactivity. Its structure makes it valuable in research for designing new biologically active compounds.
