Used primarily in the pharmaceutical industry as an intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs. It plays a key role in developing medications that manage high blood pressure and heart failure by blocking the action of angiotensin II, a substance that narrows blood vessels. Due to its specific structure, it contributes to the potency and selectivity of the final drug compound. The potassium salt form enhances solubility, which improves bioavailability in the final therapeutic agent.
