An active metabolite of macitentan (obtained by oxidative depropylation), an orphan drug used for the treatment of pulmonary arterial hypertension. It has a role as an antihypertensive agent, an endothelin receptor antagonist, a drug metabolite and a xenobiotic metabolite. It is an aromatic ether, an organobromine compound, a member of pyrimidines and a member of sulfamides. It is functionally related to an ethylene glycol."}]
