stilbene การใช้

• Stilbene and derivatives are used in scintillation counters to detect such particles.
• Stilbene is also one of the gain mediums used in dye lasers.
• Examples of the former include stilbene and azobenzene.
• The activation energy of the electrocyclization is 73 kJ mol  " 1 for stilbene.
• The stilbenoids are naturally occurring stilbene derivatives.
• Some non-stilbene brighteners are used in more permanent applications such as whitening synthetic fiber.
• Stilbene undergoes reactions typical of alkenes, being susceptible to bromination, epoxidation, and cycloaddition.
• The name stilbene is derived from the Greek word " stilbos ", which means shining.
• The stilbestrols, which are structurally but not synthetically related to E-stilbene, exhibit estrogenic activity.
• The name stilbene was derived from the Greek word " stilbos ", which means shining.
• Repeated the same pattern of vandalism on ( E )-Stilbene fiddling with its melting and boiling points.
• "' Dianethole "'is a stilbene and diethylstilbestrol, which may explain their estrogenic activity.
• "' Photoanethole "'is a stilbene and diethylstilbestrol, which may explain their estrogenic activity.
• They have two aromatic rings separated by 1-3 atoms ( often a stilbene-type of arrangement ).
• Isotopic labeling was used to confirm that " syn " elimination occurs during ester pyrolysis in the formation of stilbene.
• The stilbene derivatives are subject to fading upon prolonged exposure to UV, due to the formation of optically inactive cis-stilbenes.
• Upon irradiation it converts to " cis "-stilbene, a classic example of a photochemical reaction involving trans-cis isomerization.
• Structurally, it is a derivative of trans-stilbene, containing amino and sulfonic acid functional groups on each of the two phenyl rings.
• This is likely due to the ethyl group of the tamoxifen stilbene core that is subject to allylic oxidative activation causing DNA alkylation and strand scission.
• It is medically important due to the pharmacologically active compounds ( within the rhizome ) including quinones, triterpenoids, flavonoids, isoflavonoids and stilbene glycosides.
