04 · Handling and storage
Storing and handling (1,1'-Biphenyl)-2-ol
Storage conditions
Store in tightly closed containers in a cool, well-ventilated area away from water. Sources of ignition, such as smoking and open flames, are prohibited where o-phenylphenol is used, handled, or stored in a manner that could create a potential fire or explosion hazard.
Source: Hazardous Substances Data Bank (HSDB)
Incompatible materials
Strong oxidizers, acids, alkalis.

Reactivity
2-PHENYLPHENOL react as a weak organic acid. Exothermically neutralizes bases. May react with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides to generate flammable gas (H2) and the heat of the reaction may ignite the gas. Is sulfonated very readily (for example, by concentrated sulfuric acid at room temperature) in exothermic reactions. May be nitrated very rapidly. Nitrated phenols often explode when heated and also form metal salts that tend toward detonation by rather mild shock. Can react with oxidizing agents (NTP, 1992).
