Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and selective COX-2 inhibitors. Its structure, featuring cyano, fluoro, and carboxylic acid groups, allows for easy functionalization, especially nucleophilic substitution at the ortho-fluoro position, making it valuable in building complex molecules in medicinal chemistry. Also employed in the preparation of agrochemicals and fluorescent dyes due to its electron-withdrawing nitrile, fluoro, and carboxylic acid groups, which enhance reactivity and binding properties.
