Methylenedioxy Pyrovalerone-d8 (hydrochloride) (MDPV-d8 (hydrochloride)) contains eight deuterium atoms at the 1-pyrrolidinyl position. It is intended for use as an internal standard for the quantification of MDPV (hydrochloride) by GC- or LC-mass spectrometry. Pyrovalerone and its analogs are inhibitors of the transporters for certain monoamine neurotransmitters, including dopamine and norepinephrine, preventing their uptake.1,2 MDPV is an analog of pyrovalerone which includes the 3,4-methylenedioxy moiety found on 3,4-methylenedioxymethamphetamine, a DEA Schedule I controlled substance. While its physiological, neurological, and toxicological actions have not been characterized, MDPV has been reported by the DEA to be abused as a central nervous system stimulant.3 Its effective dose and chemical interactions are unknown, but it has been used alone and in combination with other stimulating compounds. Products containing MDPV have been marketed in Europe and Australia; they have also been seized by law enforcement in several states.3 MDPV and some of its metabolites have recently been characterized by spectroscopic analysis.4,5,6,7 MDPV is to be used in the forensic analysis of samples that may contain this compound. This product, the hydrochloride salt of MDPV, has superior solubility in aqueous solvents, compared to the free base (Item No. 10624).
