mdat mdat 6,7-methylenedioxy-2-aminotetralin (mdat) is a drug developed in the 1990s by a team at purdue university led by david e. nichols. it appears to act as a serotonin releasing agent based on rodent drug discrimination assays comparing it to mdma, in which it fully substitutes for, and additionally lacks any kind of serotonergic neurotoxicity. hence, mdat is considered likely to be a non-neurotoxic, putative entactogen in humans. mdatclinical dataroutes ofadministrationoralatc codenonelegal statuslegal status in general: uncontrolled identifiers iupac name 5,6,7,8-tetrahydrobenzobenzodioxol-6-amine cas number101625-35-8 yhydrochloride: 3446-21-8 ypubchem cid36483chemspider33531unii28ir5lc41qhydrochloride: box4u52eet ychemical and physical dataformulac11h13no2molar mass191.230 g·mol−13d model (jsmol)interactive image smiles c3cc1cc2ococ2cc1cc3n
