Used as an intermediate in organic synthesis, particularly in pharmaceuticals and agrochemicals. It serves as a building block for thiophene-based compounds, which are important in the development of active ingredients in crop protection products and medicinal agents. Its ester and thiophene functionalities allow for further chemical modifications, making it valuable in creating complex molecules. Also employed in the synthesis of conjugated polymers for electronic materials due to the electron-rich nature of the thiophene ring.
