The Uses of D-AMPHETAMINE SULFATE

Amfetamine

Manufacturing Process

Two mols, for example, 270 grams, of racemic α-methylphenethylamine base are reacted with one mol (150 grams) of d-tartaric acid, thereby forming dl-αmethylphenethylamine d-tartrate, a neutral salt. The neutral salt thus obtained is fully dissolved by the addition of sufficient, say about 1 liter, of absolute ethanol, and heating to about the boiling point. The solution is then allowed to cool to room temperature with occasional stirring to effect crystallization. The crystals are filtered off and will be found to contain a preponderance of the levo enantiomorph.
The residual solid in the mother liquors is repeatedly and systematically crystallized, yielding a further fraction of 1-α-methylphenethylamine d-tartrate which may be purified by recrystallization. d-α-Methylphenethylamine may be readily recovered from the mother liquors by the addition of tartaric acid thereto for the formation of acid tartrates and separation of d-αmethylphenethylamine d-bitartrate by crystallization.
The free base of either optical isomer may be obtained by addition to the dtartrate in the case of the levo isomer and the d-bitartrate in the case of the dextro isomer of alkali in excess, as, for example, by the addition of an aqueous solution of caustic soda, which will cause the base to separate as an oil which may be recovered and purified by any well-known procedure. The base is exactly neutralized with sulfuric acid to give the sulfate.

Therapeutic Function

Central stimulant

Biological Activity

CNS stimulant. Targets monoamine transporters to elevate synaptic levels of noradrenalin, dopamine and serotonin.

Safety Profile

Poison by ingestion, intraperitoneal, subcutaneous, and intravenous routes. A human teratogen that causes developmental abnormalities of the central nervous system. Experimental reproductive effects including other teratogenic effects. A habit-forming stimulant. When heated to decomposition it emits very toxic fumes of SO, and NO,.
