Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules due to the presence of bromine and carboxylic acid functional groups. The compound serves as a building block in cross-coupling reactions, enabling the construction of complex thiophene-based structures. These structures are valuable in the design of organic semiconductors, conductive polymers, and materials for optoelectronic devices such as organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs). Its reactivity allows for selective modifications, making it useful in medicinal chemistry for creating libraries of derivatives in drug discovery programs.
