Hazard Information | Back Directory | [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. | [Reactivity Profile]
CIS-STILBENE(645-49-8) may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen. | [Air & Water Reactions]
Sensitive to prolonged exposure to air and light [Lancaster]. Insoluble in water. | [Fire Hazard]
Flash point data for this chemical are not available, however CIS-STILBENE is probably combustible. | [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. | [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.] |
