Scientific Applications
1. Neuropharmacological Research
Serotonergic Action: Potent 5-HT₁ₐ/₂ₐ agonist, relevant for studies of consciousness modulation.
EEG/fMRI studies: Research into acute effects on brain wave patterns (e.g. gamma oscillations).
Neuroplasticity: Possible BDNF-enhancing effects (in animal models).
2. Metabolic & Toxicological Studies
MAO-dependent metabolism: Investigation of CYP2D6 and MAO-A degradation pathways.
Dose-dependent toxicity: Determination of safety margins in cell cultures.
3. Comparative Pharmacology
To DMT: Higher potency but shorter duration of action (15-30 min when inhaled).
Regarding psilocybin: Differences in receptor affinity and subjective effects.
Experimental Guidelines
Recommended Concentrations (In Vitro)
Application | Concentration range | Solvent |

Frequently Asked Questions (FAQ)
Q1: What is the difference between freebase and fumaric acid salt?
A: Freebase is more volatile (suitable for evaporation experiments), while the fumaric acid salt is more stable for solutions.
Q2: How is 5-MeO-DFT detected in toxicology screens?
A: Recognizable via:
LC-MS/MS (precursor ion m/z 219 → product ion m/z 174)
Immunoassays: Cross-reactivity with some DMT tests (≤30%).
Q3: Are there any known pharmacokinetic interactions?
A: Dangerous combinations:
MAO inhibitors (risk of serotonin syndrome).
SSRIs (reduced efficacy due to competition).
Q4: How to handle waste?
A: Inactivate with:
Dilute hydrochloric acid (0.1M) for neutralization.
Absorption with activated carbon.
Dispose of as hazardous chemical waste (UN number: 3249).
