Used as an intermediate in the synthesis of biphenyl-based pharmaceuticals, particularly in the production of angiotensin II receptor antagonists (such as sartans like losartan) used for treating hypertension. It serves as a key building block in medicinal chemistry, where the nitro group facilitates further chemical modifications to create more complex molecules with biological activity. Also employed in research for developing new organic compounds and in the synthesis of fluorescent materials and optoelectronic compounds requiring electrical conductivity and structural stability.
