Used as a key intermediate in the synthesis of anticoagulant pharmaceuticals, particularly in the development of novel factor Xa inhibitors. Its chiral structure enables selective biological activity, making it valuable in creating potent and targeted blood clotting agents. The compound's coumarin core combined with halogenated aromatic groups enhances binding affinity to specific enzyme sites, improving drug efficacy. It is also explored in medicinal chemistry for optimizing pharmacokinetic properties such as metabolic stability and oral bioavailability in new cardiovascular drugs.
