Used primarily in pharmaceutical research as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the development of antihypertensive drugs. Its structure enables strong interaction with specific cellular receptors involved in blood pressure regulation. It is also employed in the preparation of selective ligands for neurological targets due to its affinity for central nervous system receptors. Commonly utilized in structure-activity relationship (SAR) studies to optimize drug candidates for improved efficacy and metabolic stability.
