Used in pharmaceutical synthesis as a key intermediate for angiotensin II receptor antagonists, particularly in the development of sartan-class antihypertensive drugs. The tetrazole group mimics the carboxylic acid functionality, enhancing metabolic stability and bioavailability. Commonly employed in medicinal chemistry for constructing bioactive molecules due to its ability to form hydrogen bonds and improve pharmacokinetic properties. Also utilized in the preparation of enzyme inhibitors and receptor modulators in research settings.
