DPT Powder (N,N-Dipropyltryptamine) | Classic Tryptamine Research Compound | BioSynLab
BioSynLab presents pharmaceutical-grade DPT (N,N-dipropyltryptamine) powder for advanced neuropharmacological research and comparative tryptamine studies. As a homolog of DMT featuring dipropyl substitution on the side-chain nitrogen, DPT serves as a critical reference compound for investigating N-alkyl chain length effects on serotonin receptor pharmacology, duration of action, and structure-activity relationships within the classic psychedelic scaffold.
Chemical Architecture & Homologous Relationships
N,N-Dipropyltryptamine represents the third member of the N,N-dialkyltryptamine homologous series, positioned between DMT (dimethyl) and DET (diethyl) in terms of alkyl chain length:
Structural Features:
- Indole Nucleus: Maintains the essential tryptophan-derived chromophore with unsubstituted 4-, 5-, 6-, and 7-positions
- Ethylamine Side Chain: Standard C₂ linker between indole C-3 and terminal nitrogen
- N,N-Dipropyl Substitution: Two propyl groups (C₃H₇) on the side-chain nitrogen, creating increased steric bulk and lipophilicity vs. DMT
Physicochemical Properties:
- Molecular weight: 244.38 g/mol (28 mass units > DMT, 28 mass units < DET)
- Calculated LogP: 3.8 (moderate lipophilicity, increased vs. DMT)
- pKa (tertiary amine): ~8.7 (protonated at physiological pH)
- Melting point: 88-92°C (freebase)
- Boiling point: 180-190°C at 0.5 mmHg
- Chirality: Achiral (no stereocenters)
Homologous Series Comparison:
| Compound | N-Substituents | MW | LogP | Duration* |
|---|---|---|---|---|
| DMT | Dimethyl (C₁) | 232.28 | 2.8 | 15-30 min |
| DPT | Dipropyl (C₃) | 244.38 | 3.8 | 2-4 hours |
| DET | Diethyl (C₂) | 260.38 | 3.3 | 2-4 hours |
