Used primarily as an intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs. Its structure supports the development of compounds that block the action of angiotensin II, a substance in the body that causes blood vessels to narrow. By inhibiting this effect, medications derived from this chemical help relax blood vessels, lower blood pressure, and improve overall cardiovascular function. It is especially valuable in the preparation of sartan-class drugs, which are widely prescribed for hypertension and heart failure. The presence of the cyanomethyl and methylsulfonyl groups enhances binding affinity and metabolic stability in the final pharmaceutical product.
