🧪 DMNPC (3,4-Dimethyl-α-pyrrolidinononanophenone)

Forensic and Analytical Overview

1. Chemical Identification

Common name: DMNPC
Systematic name: 3,4-Dimethyl-α-pyrrolidinononanophenone
Chemical class: Synthetic cathinone / Pyrrolidinophenone derivative
Molecular formula: C₁₉H₂₉NO
Molecular weight: ~287.44 g/mol
Structural relation: Structurally related to α-PVP and MDPV, with additional methyl substitutions on the aromatic ring. Classified within the pyrrolidinophenone family of compounds.

2. Background

DMNPC emerged in the late 2010s as a research analogue within the pyrrolidinophenone subclass of synthetic cathinones.
Its structure suggests potential dopaminergic and noradrenergic activity similar to other analogues in the α-PVP series, making it of interest for forensic and analytical chemistry studies.

While chemically related to controlled stimulant compounds, DMNPC is not approved for medical or veterinary use and appears exclusively in research and analytical reference settings.

3. Analytical Characterization

Common methods of laboratory analysis include:

• Gas Chromatography–Mass Spectrometry (GC–MS)

• Liquid Chromatography–Mass Spectrometry (LC–MS)

• Infrared (IR) Spectroscopy

• Nuclear Magnetic Resonance (NMR)

• High-Resolution Mass Spectrometry (HRMS)

Characteristic fragmentation patterns show peaks typical of pyrrolidinophenones, including cleavage of the pyrrolidine ring and α-carbon fragmentation consistent with substituted cathinones.

4. Research and Forensic Relevance

DMNPC is primarily studied for:

• Analytical identification in forensic casework and chemical profiling

• Spectral database development for substituted cathinones

• Comparison of structural analogues (ring substitutions and chain length effects)

• Support in toxicological screening and metabolic pathway studies

5. Legal and Safety Notes

Status: Controlled or restricted under analogue/NPS regulations in numerous jurisdictions.
Handling: For qualified laboratory personnel only; requires appropriate chemical handling authorization.
Storage: Store securely in cool, dry, and light-protected conditions.
Safety: Use gloves, eye protection, and lab ventilation; dispose of residues in accordance with hazardous waste protocols.

6. Summary

DMNPC is a pyrrolidinophenone-class research compound encountered in forensic and analytical contexts.
It assists in broadening the understanding of structure–activity relationships and in developing robust detection methods for synthetic cathinones.
