Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of thiophene-based bioactive molecules. Its functional groups enable coupling reactions in medicinal chemistry, making it valuable for creating drug candidates with enhanced metabolic stability and receptor selectivity. Also employed in materials science for constructing conductive polymers and organic semiconductors due to the electron-rich nature of the thiophene ring. The hydrobromide salt form improves stability and handling during synthetic processes.
