Is Stilbene dibromide, Product 106550, optically active?
Generally, chiral molecules are optically active, rotating polarized light. Meso compounds, such as 106550, are unique in that there are chiral carbons in the molecule yet they are not optically active. meso-1,2-Dibromo-1,2-diphenylethane has chiral carbons that are virtually identical but the arrangement of the groups on this carbon are different; the result of these opposing effects is a net optical rotation of zero.
In what solvents is Stilbene dibromide, Product 106550, soluble?
Sigma-Aldrich does not currently test this product for solubility in a particular solvent. However, our quality control does solubilize this product with acetonitrile (with sonication) for analysis by HPLC at a concentration of 0.5mg/mL.
