This research chemical has gained significant attention in scientific communities and among researchers studying novel psychoactive substances. As a positional isomer of pyrovalerone, A-PiHP exhibits unique chemical properties that make it valuable for various research applications.
At Newchemicalz.com, we pride ourselves on providing high-quality research chemicals for legitimate scientific purposes. Our commitment to excellence ensures that researchers across the United Kingdom, United States, Germany, Australia, and Asia have access to premium-grade A-PiHP for their studies.
Chemical Structure and Properties 📊
A-PiHP, with its IUPAC name 4-methyl-1-phenyl-2-(pyrrolidin-1-yl)pentan-1-one, belongs to the substituted cathinone and pyrrolidine chemical classes. Its molecular formula is C₁₆H₂₃NO with a molar mass of 245.366 g·mol⁻¹.
The structural uniqueness of A-PiHP lies in its methyl group positioning, transferred from the 4-position of the aromatic ring to the 4-position of the acyl chain. This configuration distinguishes it from other cathinones and contributes to its distinct pharmacological profile.
📜 History and Emergence of A-PiHP 🌍
The emergence of A-PiHP in the research chemical market dates back to July 2016 when it was first identified as a designer drug by a forensic laboratory in Slovenia and reported to the EMCDDA. Since then, its presence has been documented across 30 countries and territories spanning Europe, Asia, North America, and Oceania.
According to recent studies, A-PiHP has become one of the top five synthetic cathinones seized by weight across Europe, highlighting its significance in the current research chemical landscape. The United Nations Office on Drugs and Crime has noted the increasing prevalence of this substance, leading to its placement under international control as a Schedule II controlled substance in March 2023.
“The volume of seized synthetic cathinones in Europe surged significantly between 2021 and 2022, representing about 86% of the total NPS quantity (30.8 tonnes) seized by EU Member States.” – European Monitoring Centre for Drugs and Drug Addiction & Europol, 2024
🔬 Pharmacological Effects and Mechanism of Action ⚗️
A-PiHP functions primarily as a potent norepinephrine-dopamine reuptake inhibitor (NDRI), exhibiting a pharmacological profile similar to other pyrovalerone cathinones. Research indicates that A-PiHP displays a higher selectivity for the dopamine transporter compared to α-PVP and α-PHP, making it particularly interesting for neurochemical research.
Key Pharmacological Characteristics:
- Potent DAT/NET inhibitor: A-PiHP shows in vitro potency similar to α-PVP for the dopamine transporter and slightly lower for the norepinephrine transporter
- Minimal SERT impact: Unlike many other psychoactive substances, A-PiHP has minimal effect on serotonin transporters
- High brain permeability: The lipophilic pyrrolidine ring contributes to excellent blood-brain barrier penetration
- Catecholamine selective: Acts as a selective transporter blocker without substrate-releasing properties
Studies have demonstrated that A-PiHP can induce significant increases in body temperature and locomotor activity, though higher doses (ED50: 4.0 mg/kg) are required compared to α-PVP (ED50: 1.1 mg/kg) to elicit similar effects. This difference is attributed to the approximately 40% lower Cmax levels of A-PiHP in blood and brain.
💊 Administration and Dosage Information 📏
In research settings, A-PiHP is typically administered through various routes depending on the experimental design. Understanding proper administration protocols is crucial for researchers working with this compound.
Common Administration Methods:
- Oral ingestion: Most common method for research studies
- Nasal insufflation: Used in specific pharmacokinetic studies
- Inhalation/vaping: Employed in research examining pulmonary absorption
- Intravenous administration: Used in controlled laboratory settings
- Rectal administration: Occasionally utilized in bioavailability studies
Reported research dosages of A-PiHP typically range from 1 to 50 mg, adjusted according to the route of administration and desired experimental outcomes. It’s important to note that these dosages are for research purposes only and should be handled by qualified professionals in controlled laboratory environments.
⚠️ Safety Considerations and Adverse Effects 🚨
When working with A-PiHP in research settings, understanding its safety profile and potential adverse effects is paramount. While comprehensive human safety data is limited, animal studies and case reports provide valuable insights for researchers.
Documented Adverse Effects in Research Settings:
- Cardiovascular effects: Tachycardia, hypertension, vasoconstriction
- Neurological effects: Agitation, hallucinations, delirium
- Thermoregulatory effects: Hyperthermia
- Muscular effects: Tremors, potential rhabdomyolysis
- Psychological effects: Anxiety, paranoia, psychosis
According to the World Health Organization, A-PiHP consumption has been linked to severe poisonings and fatalities in both Europe and the United States. Between January 2020 and June 2021, the US State Unintentional Drug Overdose Reporting System listed A-PiHP as the cause of death in 18 cases.
“Fatalities solely attributed to A-PiHP intoxication showed femoral blood concentrations ranging from 69 to 2377 ng/mL and brain concentrations between 230 and 1506 ng/g.” – Adamowicz et al., 2020
🌐 Legal Status of A-PiHP Worldwide ⚖️
The legal status of A-PiHP varies significantly across different jurisdictions, reflecting evolving regulatory approaches to novel psychoactive substances. Researchers must be aware of these regulations when conducting studies with this compound.
Legal Status by Region:
In March 2023, the United Nations placed A-PiHP under international control as a Schedule II controlled substance, reflecting growing concerns about its potential for abuse and associated health risks. Researchers must ensure compliance with all applicable regulations when working with this compound.
