Stilbene Uses
1. Stilbene (CAS NO.588-59-0) is used in manufacture of dyes and optical brighteners, and also as a phosphor and a scintillator.
2 Stilbene (CAS NO.588-59-0) is one of the gain mediums used in dye lasers.
3.Many stilbene derivates (stilbenoids) are present naturally in plants. An example is resveratrol and its cousin, pterostilbene.
4.Stilbene derivatives especially E(trans) isomer have estrogenic activity so used in making non-steroidal synthetic estrogens as Diethyl stilbestrol, Fosfosterol, Dienesterol
