DEFINITION
Warfarin Sodium is an amorphous solid or a crystalline clathrate. The crystalline form consists principally of warfarin sodium and isopropyl alcohol in a 2:1 molecular ratio. It contains NLT 8.0% and NMT 8.5% of isopropyl alcohol. Warfarin Sodium contains NLT 97.0% and NMT 102.0% of warfarin sodium (C19H15NaO4), calculated on the anhydrous basis for the amorphous form or on the anhydrous and isopropyl alcohol-free basis for the crystalline form.
