Can anyone tell me what is the solubility of racemic amphetamine sulfate, phosphate and hydrochloride in water at room temperature?
For sulfate, the Merck Index says 1:9 at room temp. (i.e. 1 g amphetamine sulfate needs 9 ml H2O to dissolve), which roughly agrees with 50-100 mg/ml @ 61 deg. Fahrenheit as it says on PubChem. Are these figures right, in your experience?
I haven't been able to find any reliable solubility data for hydrochloride or phosphate.
