The resulting metabolites were subsequently liquid/liquid extracted and analyzed using gas chromatography/mass spectrometry (GC/MS) as trimethylsilyl (TMS) derivatives. The structures of the metabolites were further confirmed by accurate mass measurement using a liquid chromatography/quadrupole time-of-flight (LC/QTOF) mass spectrometer. The studies demonstrated that the main metabolites of MDPV are catechol and methyl catechol pyrovalerone, which are in turn sulfated and glucuronated. ...","MolecularFormula":"C\u003csub\u003e16\u003c/sub\u003eH\u003csub\u003e21\u003c/sub\u003eNO\u003csub\u003e3\u003c/sub\u003e","MolecularWeight":"275.34 g/mol","Opticalactivity":"( + / - )","PD":"PD021354","PubChemId":20111961,"Record Description":["Wikipedia|List of designer drugs|Stimulants|Pyrrolidines and Pyrrolidinophenones"],"Records":{"UNII":{"Impurities":[]}},"RefChem":"389299","RefCount":4,"RefCur":"","References":[{"Name":"Wikipedia","Urls":[{"Link":"https://en.wikipedia.org/wiki/Methylenedioxypyrovalerone","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]},{"Name":"Wikidata","Urls":[{"Link":"https://www.wikidata.org/wiki/Q417010","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]},{"Name":"PubChem","Urls":[{"Link":"https://pubchem.ncbi.nlm.nih.gov/compound/20111961","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]},{"Name":"Probes \u0026 Drugs","Urls":[{"Link":"https://www.probes-drugs.org/compound/PD021354","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]},{"Name":"Common Chemistry","Urls":[{"Link":"https://commonchemistry.cas.org/detail?cas_rn=687603-66-3","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]},{"Name":"HMDB","Urls":[{"Link":"https://hmdb.ca/metabolites/HMDB0254640","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]},{"Name":"KEGG","Urls":[{"Link":"https://www.kegg.jp/entry/C22808","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]},{"Name":"UNII","Urls":[{"Link":"https://gsrs.ncats.nih.gov/ginas/app/ui/substances/E7LD6JMR0L","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]},{"Name":"EPA DSSTox","Urls":[{"Link":"https://comptox.epa.gov/dashboard/chemical/details/DTXSID90897461","Name":"3',4'-Methylenedioxy-α-pyrrolidinopentiophenone","Sub":false}]}],"Refs":["National Center for Biotechnology Information.
