There's no entry for M tartrate in the CAS listing in the Shulgin Index, so you might be out on a limb there and have to generate your own solubility data. Have you tried looking on PubChem?anyone have information on mescaline tartrate in ethanol 96? I’m gonna experiment a bit with sulfuric acid 30% and tartaric acid with ethanol 96 but would love some information if anyone has it
Of the Nexians, @Loveall would be the prime candidate for knowing this one.
