Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs like valsartan and related pharmaceuticals. Its structure enables the formation of biaryl motifs common in sartan-class medications, which block the action of angiotensin II, helping to relax blood vessels and lower blood pressure. It is employed in multi-step organic syntheses where selective coupling and esterification reactions are required to build the active pharmaceutical ingredient. Commonly utilized in research and industrial settings for developing cardiovascular therapeutics.
