Organic & Inorganic Chemistry
| Property | Detail |
|---|---|
| Chemical class | β‑keto phenethylamine derivative (pyrrolidinophenone family) |
| General formula | Approx. C₁₅H₂₁NO (depending on substitution) |
| Functional groups | Ketone (C=O), tertiary amine (pyrrolidine), aromatic ring, alkyl side chain |
| Physical form | Crystalline powder (moderately lipophilic) |

Chemical Biology
- Pharmacological mechanism (inferred from analogues): Reuptake inhibition of dopamine and norepinephrine transporters.
- Toxicological properties: Excessive CNS stimulation in animal models; potential for tachycardia and hyperthermia.
- Scientific relevance: Used in research for structure–activity relationships (SAR) within synthetic cathinones.
- Human use: Prohibited — no approved medicinal applications.
Computational Chemistry
- Molecular modeling: Ab initio (DFT, B3LYP / 6‑31G*) to predict lowest energy conformers.
- HOMO–LUMO Gap: 3.8 eV (predicted), indicating moderate chemical stability.
- Docking simulations: Used in comparative studies with dopamine transporters to estimate binding affinities.
- QSAR indices: Lipophilicity (log P ≈ 3.8), polar surface area (TPSA ≈ 29 Ų).
- Purpose: Academic evaluation of NPS electronic structure and bioactivity correlations.
Environmental Chemistry
- Persistence: Low volatility; moderately persistent in soil and aqueous media.
- Degradation pathways: Photolysis → hydroxylated phenones; oxidative pathways yield benzoic acid derivatives.
- Hazard classification: Toxic to aquatic organisms (Category 3, GHS).
- Disposal protocol: High‑temperature (> 1000 °C) incineration under hazardous organic waste controls.
