3-Bromo-4-fluorobenzyl Alcohol serves as a key intermediate in Suzuki-Miyaura cross-coupling reactions for pharmaceutical development. Researchers utilize this compound in the synthesis of fluorinated liquid crystals for display technologies. The bifunctional nature allows simultaneous modification of both halogen sites in medicinal chemistry applications. It’s particularly valuable for creating PET radiotracer precursors due to its fluorine content.
