Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with anti-inflammatory and antihypertensive properties. It serves as a building block in agrochemicals for the production of herbicides and pesticides due to its stable heterocyclic structure. Its carboxylic acid functionality allows for easy derivatization, making it valuable in medicinal chemistry for creating compound libraries in drug discovery. Also employed in the preparation of functionalized thiophene derivatives used in organic electronics and materials science.
