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 introducing dichlorophenyl and carboxylic acid functional groups into more complex molecules. Also employed in the development of agrochemicals and bioactive compounds due to its reactivity in condensation and cyclization reactions. Its α-keto acid structure makes it valuable in forming heterocyclic systems important in medicinal chemistry.
