I know from the literature that the following compounds have decreasing polarity: Rosmarinic Acid -> TMF -> Sinensetin
and I guess comparing compounds of similar structure it is manageable to compare bond types, groups etc etc by which to order their polarity, but what about compounds with very different structures, groups and bonds, especially when you want to rapidly order 10's-100's of compounds.
My questions:
Is there such a thing as an absolute measure of "polarity" for a compound by which other compounds can be compared/ordered?
Depending on 2) is there a resource whereby you can lookup your compound to obtain its polarity?
I am asking this question from a Chromatography perspective. I would like to know the order of separation for a group of compounds and how to know what "polarity" of mobile phase to start my experimentations with.
