Introduction to MDPHP Powder (Monkey Dust)

Monkey dust |MDPHP (3,4-Methylenedioxy-α-pyrrolidinohexiophenone), commonly known as “Monkey Dust,” is a potent synthetic cathinone belonging to the pyrrolidinophenone class of compounds. It is a higher homologue of MDPV, distinguished by an extended alkyl chain containing six carbon atoms . MDPHP first appeared on world drug markets around 2014–2015 and has since been reported to the EU Early Warning System almost annually by several European countries .

The term “Monkey Dust” is a collective street name that may refer to MDPHP or other pyrrolidinophenone cathinones such as α-PiHP or α-PHP, though MDPHP is most commonly associated with this designation . As a research chemical, MDPHP is primarily utilized as a certified reference material for forensic and toxicological applications, including HPLC-MS/MS method development and quality control . At 4mmcchems, we supply premium-grade MDPHP Powder to researchers and professionals worldwide, with a focus on fast, discreet shipping across Europe.

Chemical Properties and Mechanism of Action

MDPHP acts primarily as a norepinephrine-dopamine reuptake inhibitor (NDRI), increasing the concentration of these neurotransmitters in the synaptic cleft . Research demonstrates that MDPHP potently inhibits the dopamine transporter (DAT) and norepinephrine transporter (NET) with high selectivity over the serotonin transporter (SERT).

Key Pharmacological Data

• DAT Inhibition (IC₅₀): 50 nM – demonstrating potent dopamine reuptake inhibition

• NET Inhibition (IC₅₀): 60 nM – also highly potent at inhibiting norepinephrine uptake

• SERT Inhibition (IC₅₀): 9,000 nM – negligible activity, resulting in a DAT/SERT selectivity ratio of 180

• Potency Comparison: MDPHP is approximately 10 times more potent than cocaine at inhibiting dopamine reuptake

• Behavioral Effects: In animal studies, MDPHP increases locomotion, aggression, heart rate, and blood pressure

Analytical Detection

For forensic laboratories, MDPHP can be identified through characteristic mass spectrometric transitions, with the protonated molecule at m/z 290.17507 and product ions at 219.1024, 149.0241, and 140.1441 . Documented postmortem femoral blood concentrations in fatal cases range from 350 to 1,639 ng/mL .
