Used in the synthesis of pharmaceuticals, particularly as an intermediate in the production of non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a building block in organic reactions where a substituted phenylacetic acid moiety is required. Its structure allows for easy functionalization, making it valuable in drug development and medicinal chemistry research. Also employed in the preparation of agrochemicals and specialty chemicals due to its aromatic and carboxylic acid properties.
