Any member of the class of biphenyls that has one or more hydroxy groups attached to the benzenoid ring system.
| Member | Definition | Role |
|---|
| 2-phenylphenol | A member of the class of hydroxybiphenyls that is biphenyl substituted by a hydroxy group at position 2. It is generally used as a post-harvest fungicide for citrus fruits. | biphenyl-2-ol |
| 2,2'-biphenol | A member of the class of hydroxybiphenyls carrying hydroxy groups at positions 2 and 2'. | biphenyl-2,2'-diol |
| 2,3-dihydroxybiphenyl | A member of the class of hydroxybiphenyls that is 1,1'-biphenyl substituted by hydroxy groups at positions 2 and 3. | biphenyl-2,3-diol |
| 3-hydroxybiphenyl | A member of the class of hydroxybiphenyls that is phenol in which the hydrogen at position 3 has been replaced by a phenyl group. | biphenyl-3-ol |
| 3,3',5,5'-tetrachlorobiphenyl-4,4'-diol | A member of the class of hydroxybiphenyls formed formally by chlorination of biphenyl-4,4'-diol at C-3, -3', -5 and -5'. | 3,3',5,5'-tetrachlorobiphenyl-4,4'-diol |
| 4-phenylphenol | A member of the class of hydroxybiphenyls that is biphenyl carrying a hydroxy group at position 4. | biphenyl-4-ol |
| 4,4'-dihydroxybiphenyl | A member of the class of hydroxybiphenyls that is biphenyl with hydroxy groups at positions 4 and 4'. | biphenyl-4,4'-diol |
| altenusin | A carboxybiphenyl that is [biphenyl]-2-carboxylic acid which is substituted by a hydroxy group at positions 3, 4' and 5', methoxy group at position 5 and a methyl group at position 2'. It is a a metabolite isolated from Alternaria and several other fungal species. | altenusin |
