Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs like valsartan and related sartan-class medications. Its structure allows for the construction of the core benzyl amino acid framework essential for biological activity in these pharmaceuticals. Commonly employed in multi-step organic synthesis due to its protected amine group and reactive ester functionality, enabling peptide-like coupling and subsequent cyclization reactions. Widely utilized in the pharmaceutical industry for large-scale manufacturing of cardiovascular drugs.
