Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antidiabetic and antihypertensive drugs. Its structure, featuring amino, bromo, and carboxylic acid groups on a thiophene ring, allows for easy functionalization, making it valuable in creating active pharmaceutical ingredients (APIs) with heterocyclic cores. Also employed in agrochemical research for designing new pesticides and herbicides due to its stability and reactivity. Commonly utilized in organic synthesis to build complex thiophene-based compounds for materials science, including semiconducting polymers and organic electronic devices.
