Used as a key intermediate in the synthesis of rivaroxaban, a potent oral anticoagulant that inhibits Factor Xa in the blood coagulation cascade. This dithiophene analog plays a critical role in constructing the core structure of the drug, enabling efficient large-scale production. Its design supports high selectivity and yield during coupling reactions, making it valuable in pharmaceutical manufacturing. Due to its stability and reactivity profile, it is preferred in multi-step synthesis routes aimed at producing high-purity rivaroxaban for tablet formulations.
