Descriptions:
pubchem: Biphenyl-4,4'-diol is a member of the class of hydroxybiphenyls that is biphenyl with hydroxy groups at positions 4 and 4'. It derives from a hydride of a biphenyl.
chebi: A member of the class of hydroxybiphenyls that is biphenyl with hydroxy groups at positions 4 and 4'.
chembl: Unnamed Compound is a small molecule listed in the ChEMBL database but has not progressed to an approved clinical phase.
wikipedia: In organic chemistry, a biphenol refers to compounds with the formula (C6H4OH)2.  Such compounds formally result from the coupling of two phenols.
