Rivaroxaban (CAS 366789-02-8), chemically identified as an oxazolidinone derivative, is a potent, direct Factor Xa inhibitor utilized as an active pharmaceutical ingredient (API). Often referred to by its development code BAY 59-7939, this crystalline powder functions by interrupting the intrinsic and extrinsic pathways of the blood coagulation cascade, preventing thrombin generation. It is extensively utilized as the primary bioactive component in the industrial manufacturing of oral anticoagulant formulations for thrombosis prevention and stroke risk reduction. We provide this industrial material with competitive factory pricing to support continuous manufacturing operations, alongside options for customized specifications. Essential technical documentation, including MSDS, TDS, COA, is readily available for all bulk supply orders.
