Used as a key intermediate in the synthesis of valsartan, an angiotensin II receptor blocker (ARB) prescribed for the treatment of hypertension. It plays a critical role in the pharmaceutical manufacturing process, enabling the stepwise construction of the active drug molecule. Due to its structural similarity to valsartan without the valine moiety, it allows for selective chemical modifications to optimize yield and purity during production. Its controlled use ensures efficient large-scale synthesis of the final active pharmaceutical ingredient (API) used in cardiovascular medications.
