• XLogP: 2.0
• XLogP3: 2.5 (PubChem)

• Stability/Degradation: Oxidation to DMT N-Oxide (yellow oil) in extended presence of oxygen (specialy in evaporation of dmt-containing solvents with heat and/or fan or generally in prolonged exposure to open air). N-oxide may be reverted back to the parent compound by reduction, as described in the N-Oxide to Freebase Wiki.

Soluble in naphtha, hexane, heptane but almost insoluble in these solvents at freezing temperatures

Almost insoluble in water.

DMT N-Oxide

• Appearance: Basic oil (Weak base. Weaker than DMT, NMT or tryptamine.) Fish et al. 1956. Hygroscopic solid Banerjee & Ghosal 1969
• XLogP3: 2

• Solubility:

Soluble in Xylene, Toluene, Limonene (?) Soluble in chloroform Bane1 and Ghosal 1969 Soluble in water. Fish et al. 1955 and Ghosal et al. 1970b and Banerjee & Ghosal 1969

Insoluble in petroleum (naphtha) but appreciably soluble in petroleum which contains fats. Ghosal & Banerjee 1969

• Interconversion: DMT N-Oxide can be reconverted back to DMT by redissolving in dilute acetic acid solution, adding excess zinc dust, mixing for a couple of hours, filtering to remove zinc, adding base and pulling with organic solvent as in a normal extraction. DMT can be oxidized by using hydrogen peroxide (Fish et al 1955)
