I'm planning to pick up some crystal MDMA next month, the seller is well-known and claims it was made from safrole, so I am interested in testing the optical isomerism of it. I believe this could be accomplished relatively easily at home with a simple set up, although I would of course appreciate input/"you're dumb, that wouldn't work because..." from someone with better chem knowledge than me.
The basis of my plan is I have a pair of polarising sunglasses to hand, and in theory a balanced mix of isomers as Sprout reckons safrole-derived MDMA should contain would produce no rotation of polarised light. Obviously I'd test the setup with, say, D-phenylalanine or some other easily available chiral compound to make sure a null signal is actually due to the isomers present and not just a non-functional setup, but if the theory holds it would give some actual data to work with, and the setup could be easily duplicated by anyone else, so if say Sid still has some of the crystal he was munching on a few weeks back that he reckoned was PMK-gly derived, we could actually test if there is a different ratio of isomers present, at least qualitively.
