I put my sample through the polarimeter after all the resolution steps etc and obtained an optical purity of 150% which is not possible lol. However i am unsure as to what could of have contributed to such a high optical purirty i was told possibly a impurity with a higher specific rotation could have resulted in this but i cant think of such an impurity. Does anyone have any ideas for this very bad result?
ps.it would be great to get a 150%. wouldnt all organic chemists love that
