Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of fluorinated aromatic compounds. Its reactive fluorosulfonyl and carboxylic acid groups allow for selective derivatization, making it valuable in medicinal chemistry for constructing sulfonamide and ester linkages. Commonly employed in the development of bioactive molecules where fluorine incorporation enhances metabolic stability and binding affinity. Also utilized in materials science for designing functional polymers with specific electronic or thermal properties.
