hi, excuse me, when you say "We precipitate d-amphetamine with an additional amount of d-tartaric acid.", how much d-tartaric acid is used? thanks.

Would the lack of solubility of d-aspartic acid in isopropyl alcohol be a problem?

Would Camphorsulfonic acid work?
Otherwise I will buy Tartaric Acid from China.
handleI don't know for sure. Probably. There are questions about its solubility and amphetamine adduct solubility with this acid.
