C6H5CH:CHC6H5 Colorless crystals soluble in ether and benzene, insoluble in water; melts at 124°C; used to make dyes and bleaches and as phosphors. Also known as diphenylethylene; toluylene.



an aliphatic-aromatic hydrocarbon; the trans form of 1,2-diphenylethylene (C6H5—CH═CH—C6H5; the cis form is known as isostilbene). Stilbene is obtained as colorless crystals that are readily soluble in regular organic solvents but insoluble in water. The melting point is 124°C, and the boiling point 306°-307°C. Stilbene crystals are used in scintillation counters, and certain stilbene derivatives are used as pharmaceuticals, for example, diethylstilbesterol, and as optical bleaches and azo dyes.
