Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. It reacts readily with amines and alcohols to form amides and esters, making it valuable for constructing complex molecules. Its thiophene ring contributes electron-rich characteristics, enhancing reactivity in cross-coupling reactions. Commonly employed in the development of bioactive compounds, including potential drug candidates targeting inflammation and central nervous system disorders. Also utilized in the synthesis of functional materials and specialty polymers where sulfur-containing building blocks are required.
