Used as an intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs like valsartan and losartan. Its structure allows for effective coupling in biphenyl tetrazole formations, which are critical for the biological activity of these medications. Also employed in agrochemical research for developing new herbicides and plant growth regulators due to its halogenated aromatic backbone and stable tetrazole ring.
