Abstract
Methods, compositions and kits are disclosed. The compounds disclosed comprise an amphetamine moiety and a methamphetamine moiety linked together by a first linking group. A second linking group depends from the first linking group and comprises a functional group. The distance of the amphetamine moiety and the methamphetamine moiety from the point of linkage of the second linking group to the first linking group is approximately the same. The compounds may be linked to labels and used in assays for the detection of amphetamine and/or methamphetamine in samples suspected of containing these drugs.
