6-Chloro-MDMA

6-Chloro-MDMA (6-Cl-MDMA, 2-Cl-4,5-MDMA) is a derivative of the amphetamine drug MDMA, which has been identified both in seized "ecstasy" tablets and in urine samples from drug users. It is thought most likely to be an impurity from synthesis and its pharmacological properties have not been established; however, it has been banned in several countries.
