Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for heterocyclic compounds due to the presence of both thiophene and carboxylic acid functional groups, enabling coupling reactions and metal-catalyzed transformations. Also employed in the preparation of organic semiconductors and conjugated polymers for electronic applications, where the thiophene moiety contributes to electron delocalization and stability. Its structure supports use in materials science for designing sensors and optoelectronic devices.
