Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of angiotensin II receptor antagonists like losartan and other sartan-class drugs for treating hypertension. It serves as a key building block due to its biphenyl structure with a carboxylic acid group, enabling coupling reactions in drug development. Also employed in the preparation of liquid crystals and organic electronic materials where substituted biphenyl motifs are required for desired physical and electronic properties. Its chloro substituent allows further functionalization, making it valuable in medicinal chemistry and materials science.
