Used as a key intermediate in the synthesis of rivaroxaban, an oral anticoagulant that inhibits Factor Xa. It plays a critical role in the pharmaceutical manufacturing process, enabling the stepwise construction of the active drug molecule. Due to its structural similarity to the core of rivaroxaban, it allows for selective chemical modifications to produce the final active pharmaceutical ingredient with high purity and yield. Its application is primarily confined to controlled laboratory and industrial settings for drug development and large-scale production.
