Used primarily in scientific research to study the prostacyclin receptor (IP receptor) due to its high selectivity as an antagonist. It helps investigate the role of prostacyclin signaling in processes such as vasodilation, platelet aggregation, and inflammation. Commonly applied in cardiovascular and pulmonary studies to understand receptor function and to evaluate potential therapeutic targets. Also utilized in pharmacological assays to block IP receptor activity and assess downstream effects in cell and tissue models.
