Dehydro Olmesartan（Cat No.:R013381）is a structural analog and metabolite-related form of olmesartan, an angiotensin II receptor blocker (ARB) that targets the renin–angiotensin system to regulate vascular tone and blood pressure. The dehydro modification alters its chemical properties, making it a valuable intermediate for studying olmesartan metabolism, degradation pathways, and analog development. Researchers use Dehydro Olmesartan in cardiovascular pharmacology and medicinal chemistry to investigate receptor binding, structure–activity relationships, and stability profiles. Its defined scaffold supports the design of novel ARB derivatives for hypertension and cardiovascular disease research.
