Used in the synthesis of heterocyclic compounds, particularly in the development of pharmaceuticals and agrochemicals. Its tetrazole ring serves as a bioisostere for carboxylic acid groups, enhancing metabolic stability and improving bioavailability in drug design. Commonly employed in the preparation of angiotensin II receptor antagonists, which are important in treating hypertension and heart failure. Also utilized in coordination chemistry as a ligand for metal ions, contributing to the formation of functional materials and catalysts. Its hydroxyl group allows for further chemical modifications, enabling the creation of esters, ethers, or conjugates for targeted applications in medicinal chemistry.
