Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and vasodilators. It serves as a building block in organic chemistry for constructing more complex molecules due to its reactive acetic acid side chain attached to the thiophene ring. Employed in research and development of new therapeutic agents, especially those targeting cardiovascular and central nervous system disorders. Also utilized in the preparation of specialty chemicals and agrochemicals where thiophene derivatives are required.
