Sorry for long time no look into this!
Well I was about to take a spectra of my Harmaline / Harmine mixture, which would be interesting of course by its own, but also to identify how pure it is by the method I did (and nearly all of us do) AND to identify what is the ratio between Harmaline and Harmine.
Sadly the Freebase does not dissolve in MeOD, not in DMSO, not in CDCl3.
Of course to a lesser extent so that the solvent gets coloured, but just by eye I would say that 90%+ stays undissolved ...
Therefore with that Freebase I had no chance to get a suitable sample for a NMR Analysis. I also tried the Salt Form, but 20 mg did also not dissolve in 0,6 ml Water, only to a negligible extent. Even heating the solvents to their vap temp did not change anything. Therefore I have abandoned this so far, but possibly I may try it later.
But beware, I have other good news!!
I have more analysis to share with you and this time much more interesting and also much more data.
I just would prefer to start an own thread ... because of 2 Reasons.
A) I will possibly expand that post over time more and more and it would be nice if every info is as compressed as possible.
B) If I post it here is may somehow get *lost* and overseen as this thread may expand further in the future.
Therefore it would be cool if I would be allowed to start a new thread, which won't get merged into this one.
