A synthetic anticoagulant drug (also known as dicoumarol) used to prevent blood clots by interfering with vitamin K metabolism.
From 'bis-' (twice) plus 'hydroxy-' (containing hydroxyl groups) plus 'coumarin' (a chemical compound), constructed using systematic chemical nomenclature.
This drug was discovered accidentally when cattle eating moldy clover developed bleeding disorders, leading scientists to isolate the compound and repurpose it as a lifesaving anticoagulant used in millions of people today.
