Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs such as losartan and other angiotensin II receptor antagonists. Its structure allows for effective coupling in heterocyclic compound formation, making it valuable in medicinal chemistry for developing bioactive molecules. Also employed in agrochemicals to enhance the stability and reactivity of certain crop protection agents. Its carboxylic acid and methoxy functional groups enable easy modification for use in various organic syntheses.
