Insoluble in water.

Reactivity Profile

Simple aromatic halogenated organic compounds, such as 4-Chlorobiphenyl, are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Fire Hazard

Flash point data for 4-Chlorobiphenyl are not available. 4-Chlorobiphenyl is probably combustible.
