Show simple item record. Chiral separation of the enantiomers of ephedrine, amphetamine, methamphetamine, MDA, MDMA, and phentermine in blood using LC-MS/MS

Adderall does not contain methamphetamine. Phentermine (Adipex) is distinguished from amphetamine and methamphetamine during DRUGSCAN confirmation testing.

As a positional isomer, it shares a molecular weight and fragment pattern nearly indiscernible from methamphetamine by many LC-MS/MS methods. This assay showed good chromatographic separation of methamphetamine, amphetamine, and phentermine (Figure 1), permitting clear differentiation between these positional isomers.

There was baseline separation between derivatized amphetamine, phentermine, internal standard, methamphetamine, and MDMA for trifluoroacetyl, pentafluoropropyl, and heptafluorobutyl derivatives. The phentermine peak eluted after the amphetamine peak and before the internal standard (Fig. 1).
