Product Description:

4-Bromo-4'-hydroxybiphenyl is a biphenyl derivative featuring a bromine atom at the 4-position and a hydroxyl group at the 4'-position. Its molecular formula is C12H9BrO, with a molecular weight of 249.10 g/mol. The compound serves as a key building block in organic synthesis, particularly for constructing biaryl structures via cross-coupling reactions such as Suzuki or Buchwald-Hartwig couplings. In pharmaceutical research, it is widely utilized as a small molecule fragment for the synthesis of potential drug candidates, including non-steroidal anti-inflammatory agents and kinase inhibitors. The hydroxyl group allows for further functionalization, such as etherification or esterification, to modulate biological activity. Additionally, in materials science, this compound is employed as a precursor for organic light-emitting diode (OLED) materials and liquid crystalline polymers, where the biphenyl core contributes to thermal stability and charge transport properties. The compound is typically a white to off-white crystalline solid, stable under normal conditions but should be stored in a cool, dry place away from strong oxidizers. It is classified as an irritant and requires standard laboratory safety handling.
