4,4′-Biphenol is an organic compound with the formula (C₆H₄OH)₂/ It is one of three symmetrical isomers of biphenol. It is a colourless crystalline solid with a high melting point. It is primarily used in the production of polymers, particularly liquid crystals where it imparts high thermal stability, and PPSU-type polysulfone (also called polyphenylenesulfone, or Radel R).
