Azilsartan is a selective angiotensin II type 1 (AT1) receptor blocker (ARB) used as an active pharmaceutical ingredient (API) in the development and research of antihypertensive drugs. It antagonizes the binding of angiotensin II to AT1 receptors, thereby relaxing blood vessels, reducing blood pressure, and mitigating risks associated with hypertension such as strokes, heart attacks, and kidney issues. This product is supplied as a high-purity reference standard (≥98% by HPLC) for laboratory, analytical, and pharmaceutical research applications. It is typically a white to beige powder, soluble in DMSO, and conforms to structural identity by infrared spectroscopy. Not intended for direct human or veterinary use.
