It is not even polar, but I have noticed that it is a good solvent for almost all the compounds that I work with in my labs. What makes it such a good solvent?
Good question. Had the same question about good solvent in asking why are so many structurally good solvents excellent solvents for stearic acid, and why acetonitrile is not. Need to do the stoichiometry: assuming a "good solvent" means the ratio in a saturated solution are solvent 10 moles (or less) to 1 mole solute, the property can include major solvent-solute interactions. If "good solvent" equals one molar, then solvent-solvent interactions clearly dominate the solvent space. Affinity of one CS2 molecule for another can be rather weak which in turn can correlate with other chemical structures more easily dispersed among CS2 molecules. . . .
