MDPV ( Methylenedioxypyrovalerone ) is a stimulant of the cathinone class which acts as a norepinephrine-dopamine reuptake inhibitor (NDRI). It was first developed in the 1960s by a team at Boehringer Ingelheim. MDPV remained an obscure stimulant until around 2004 when it was reportedly sold as a designer drug. Products labeled as bath salts containing MDPV were previously sold as recreational drugs in gas stations and convenience stores in the United States, similar to the marketing for Spice and K2 as incense
The hydrochloride salt exists as a very fine, hygroscopic, crystalline powder that tends to clump to itself, resembling something like powdered sugar. Its color can range from pure white to a yellowish-tan and has a slight odor that strengthens as it colors. Impurities are likely to consist of either pyrrolidine or alpha-dibrominated alkylphenones from either excess pyrrolidine or incomplete amination, respectively, during synthesis. These impurities likely account for its discoloration and fishy (pyrrolidine) or bromine-like odor, which worsens upon exposure to air, moisture, or bases.
3,4-Methylenedioxypyrovalerone (also known as MDPV, NRG-1, and imprecisely as Bath Salts, among many others) is a novel, extremely potent synthetic stimulant substance of the cathinone and pyrrolidine chemical classes that produces states of extreme stimulant euphoria, disinhibition, and sexual arousal when administered. MDPV is thought to act primarily as as a norepinephrine-dopamine reuptake inhibitor (NDRI) and possesses powerful euphoric stimulant qualities. It was first developed in the 1960s by a team at Boehringer Ingelheim.
MDPV remained an obscure stimulant until around 2004, when it was reportedly first made available to the public as a designer drug. Products labeled as “bath salts” containing MDPV were previously sold as recreational drugs in gas stations and convenience stores in the United States, similar to the marketing strategy of Spice and K2 as incense.
Historical reports show records of the preparation of MDPV for potential use as a CNS stimulant. It was claimed to have potential to be an alternative for racemic amphetamine and, although showing some desirable qualities such as reduced toxicity as compared to amphetamine, MDPV was chosen to not be developed as a medicinal drug.
