Coumadin (crystalline warfarin sodium), a vitamin K-dependent anticoagulant factor, is crystalline sodium warfarin isopropanol clathrate. The crystallization of warfarin sodium virtually eliminates trace impurities present in amorphous warfarin sodium, thus achieving a crystalline product of the highest purity. Warfarin is the coined generic name for 3-(a-acetonyl-benzyl)-4-hydroxycoumarin. Its empirical formula is C19H15NaO4.
Crystalline warfarin sodium occurs as a white, odorless, crystalline powder, discolored by light and very soluble in water; freely soluble in alcohol; very slightly soluble in chloroform and in ether.
