Description
4-MEO-PV9 (4-methoxy-PV9) is a synthetic research chemical from the group of α-Pyrrolidinophenone, which is arousing increasing interest in modern neurochemical and pharmacological research.
It is closely related to other cathinone derivatives such as 4-MEO-PV8 or α-PVP, but differs in that it has an extended side chain and the characteristic methoxy group in the para position of the aromatic ring.
This structural variation leads to altered physicochemical properties and makes 4-MEO-PV9 a particularly valuable substance for experimental studies in the field of neurotransmission.
In the Neuroscience 4-MEO-PV9 serves as a reference compound for studying signal transmission and receptor binding in the central nervous system.
Research groups use it to understand the interactions of synthetic stimulants with monoamine transporters and their effects on neuronal activity.
As the compound is intended for laboratory use only, it must not be used for human consumption or therapeutic applications.
Chemical structure and properties
Chemically, 4-MEO-PV9 belongs to the family of Cathinone, characterized by a keto group at the β-position of the alkyl chain.
Within this group, it is one of the so-called α-Pyrrolidinophenones, which are characterized by a pyrrolidine ring structure.
The methoxy substitution at the fourth position of the phenyl ring changes both the polarity and the lipophilicity of the compound and can influence the binding affinity to neurotransporter proteins.
Important chemical parameters
- Chemical name: 1-(4-methoxyphenyl)-2-(pyrrolidin-1-yl)octan-1-one
- Sum formula: C19H29NO2
- Molecular weight: approx. 303.4 g/mol
- Purity: ≥98 % (analytically tested using HPLC or GC-MS)
- Form of appearance: white to slightly beige crystalline powder
- Solubility: Soluble in ethanol, methanol and acetone; limited solubility in water
- Stability: Sensitive to light and heat; store in a cool, dry place
Due to its structural stability, the compound is well suited for chromatographic and spectroscopic investigations.
It is often used for quality testing by Gas chromatography-mass spectrometry (GC-MS) or Nuclear magnetic resonance spectroscopy (NMR) analyzed.
These methods ensure precise identification and purity determination, which is essential for reproducible research results.
Pharmacological and neurochemical relevance
4-MEO-PV9 is used in basic pharmacological research as a Model substance for monoaminergic stimulants used.
It serves to investigate how structural modifications within the pyrrolidinophenone class influence the activity of dopamine, noradrenaline and serotonin transporters.
These studies contribute to a better understanding of the interplay between chemical structure and pharmacological effect.
The methoxy group at the 4-position of the phenyl ring changes the electronic density of the molecule, which can lead to an altered binding affinity to certain receptor sites.
This allows differences in duration of action, potency and receptor preference to be recorded in comparison to non-substituted derivatives such as α-PVP or PV9.
Typical research questions
- How does methoxy substitution influence the binding affinity to dopamine transporters (DAT)?
- Does the lipophilic characteristic and thus the blood-brain barrier passage change?
- Which metabolites are produced during in vitro simulations of enzymatic processes?
- How do chemical structural changes correlate with neurochemical activity?
Such questions are crucial in order to develop new models for neuronal signal transmission and to better classify the toxicological risks of synthetic cathinones.
