Organic / Inorganic Chemistry
| Property | Specification |
|---|---|
| IUPAC Name | N‑methyl‑1‑(4‑chlorophenyl)propan‑2‑amine |
| Formula | C₁₀H₁₄ClN |
| Molecular Weight | 183.68 g · mol⁻¹ |
| Functional Groups | Secondary amine (N‑CH₃), para‑chloro‑substituted aryl ring, aliphatic hydrocarbon chain |
| Physical Form | Crystalline powder (often HCl salt in research grade) |
| Melting Point (HCl salt) | ≈ 172–174 °C |

Chemical Biology
- Classification: Substituted amphetamine analog with psychostimulant properties.
- Mechanism: Monoamine transporter substrate — stimulates dopamine (DA) and norepinephrine (NE) release.
- SAR Insight: Chloro‑substitution increases lipophilicity and extends half‑life relative to methamphetamine.
- Metabolism: N‑demethylation → 4‑chloramphetamine; oxidative deamination by MAO → 4‑chlorophenyl‑acetone intermediate; further oxidation to benzoic acids.
- In vitro use: Standard for mass‑spectral method validation and forensic toxicology training.
- Safety note: Neurotoxic to serotonergic and dopaminergic cells in biological systems — for research use only.
Computational Chemistry
| Parameter | B3LYP/6‑31G* Prediction |
|---|---|
| Dipole Moment | 2.7 Debye |
| HOMO–LUMO Gap | ≈ 5.1 eV |
| Predicted log P | 2.75 – 2.9 |
| pKa (amine) | 9.6 |

| Insights: Chlorine atom improves membrane partitioning and moderately enhances dopamine transporter affinity over non‑halogenated analogues. |
Environmental Chemistry
- Hydrolysis: Minimal under neutral conditions.
- Photolysis: Degrades slowly under UV, producing 4‑chlorobenzaldehyde and amine residues.
- Soil Mobility: Low (volatility) and moderate organic sorption.
- Biodegradability: Limited; potential persistence in aquatic sediments.
- Waste Handling: Treat as hazardous organic compound — incineration at > 1100 °C.
- Hazard: Persistent organic pollutant potential under improper disposal.
