Reactivity Profile
Ortho-phenylphenol reacts as a weak organic acid.
Neutralizes bases exothermically.
Hydrides can react with strong reducing agents such as nitrides, alkali metals and sulphides to form flammable gas (H2), and the heat of reaction can ignite the gas.
2-Phenylphenol is very easily sulfonated in exothermic reactions (for example, with concentrated sulfuric acid at room temperature).
It can be nitrated very quickly.
Nitrated phenols generally explode when heated and also form metal salts that tend to explode on a fairly mild shock.
2-Phenylphenol May react with oxidizing agents

general information
Ortho-phenylphenol and its water-soluble salt, sodium ortho-phenylphenate, are antimicrobial agents used as bacteriostats, fungicides, and disinfectants.
Both have been used in agriculture to control fungal and bacterial growth in stored products such as fruits and vegetables.
Most agro-food applications have been abandoned, but Ortho-phenylphenol is still used in pears and citrus fruits.
Ortho-phenylphenol is still used in industrial applications, as a disinfectant fungicide in ornamental plants and lawns, in paints and as a wood preservative.
In the past, ortho-phenylphenol was used in household disinfectants for surfaces.
Ortho-phenylphenol is volatile and has limited solubility in water.
Both chemicals degrade in the environment within hours or weeks.
may occur via the dermal, inhalation or oral routes from residential use and ingestion of processed food or food in contact with processed surfaces or equipment.
Ortho-phenylphenol was detected in 40 out of 60 different canned beers at low concentrations per billion.
Estimated human intakes are below recommended intake limits.
Workers who manufacture, formulate, or apply these chemicals may be more exposed than the general population.
Ortho-phenylphenol is effectively absorbed from the gastrointestinal tract and through the skin and is rapidly eliminated from the body as OPP glucuronide and sulfate conjugates.
Current evidence indicates that Ortho-phenylphenol does not accumulate in the body; however, it has been measured in small amounts in human adipose tissue.

Ortho-phenylphenol is often applied for post-harvest treatment of fruits and vegetables to protect against microbial damage.
Ortho-phenylphenol is also used for waxing citrus fruits and disinfecting seed boxes.
It has been reported that 2-phenylphenol has some toxic effects on humans due to the discharge of ortho-phenylphenol into the environment.
Therefore, it is important to prepare selective materials for the extraction of 2-phenylphenol.
For this purpose, molecular imprinter polymer was prepared by precipitation polymerization using a non-covalent approach using 2-phenylphenol as template molecule, styrene as functional monomer and divinyl benzene as crosslinker.
