Chemical Properties
pale yellow liquid
Uses
cis-Stilbene: stilbene and its natural derivatives such as resveratrol and vitisins inhibits Staphylococcus aureus hemolytic activity and biofilm formation without affecting its bacterial growth
Definition
ChEBI: Cis-stilbene is the cis-isomer of stilbene.
General Description
Oily yellow liquid. Freezing point 5°C. Insoluble in water. Soluble in ethanol. Unstable relative to the trans isomer, which is a solid with a melting point of 122-124°C.
Air & Water Reactions
Sensitive to prolonged exposure to air and light [Lancaster]. Insoluble in water.
Reactivity Profile
CIS-STILBENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen.
Fire Hazard
Flash point data for CIS-STILBENE are not available, however CIS-STILBENE is probably combustible.
Purification Methods
Purify it by chromatography on alumina using hexane and distil it under vacuum. (The final product contains ca 0.1% of the trans-isomer.) [Lewis et al. J Am Chem Soc 107 203 1985, Saltiel J Phys Chem 91 2755 1987, Beilstein 5 H 630.]
