Biphenol, also known as p-phenyl phenol, is the intermediates of the fungicide bitertanol.It is used in the synthesis of oil-soluble resin and emulsifier; used as a component of corrosion-resistant paint, printing and dyeing carrier. P-hydroxybiphenyl synthesized red light enhancement and green light enhancement materials are one of the main raw materials for color films and are also used as analytical reagents.

Fluorescence and phosphorescence quantum yields and fluorescence and phosphorescence lifetimes were obtained for 4-phenylphenol adsorbed on filter paper with either NaCl, NaBr, or NaI at 296 and 93 K. The solid-surface fluorescence and phosphorescence quantum yield values and phosphorescence lifetime values were obtained for p-aminobenzoic acid (PABA) and 4-phenylphenol adsorbed on α-cyclodextrin/NaCl mixtures. 4-Phenylphenol is used as an antioxidant and is a potential EDC.
