Abstract

The disclosure relates to (2-{4-[(methoxycarbonyl)oxy]-1H-indol-3-yl}ethyl)bis(propan-2-yl)azanium chloride (4-methylcarbonato-N,N-diisopropyltryptramine chloride or 4-methylcarbonato-DiPT chloride), crystalline 4-methylcarbonato-DiPT chloride, [2-(1H-indol-3-yl)ethyl](propan-2-yl)amine (N-isopropyltryptamine or NiPT), crystalline NiPT, N-[2-(1H-indol-3-yl)ethyl]propan-2-amine hydrobromide (N-isopropyltryptamine hydrobromide or NiPT hydrobromide), crystalline NiPT hydrobromide, N-[2-(1H-indol-3-yl)ethyl]cyclohexanamine (N-cyclohexyltryptamine), crystalline N-cyclohexyltryptamine, 2-(1H-in-dol-3-yl)ethanamine (tryptamine), crystalline tryptamine, N-[2-(1H-indol-3-yl)ethyl]cyclohexanamine hydrobromide (N-cyclohexyltryptamine hydrobromide), crystalline N-cyclohexyltryptamine hydrobromide, and specific crystalline forms thereof, including crystalline form 1 of 4-methylcarbonrato-DiPT chloride, crystalline form 1 of NiPT, crystalline form 1 of NiPT hydrobromide, crystalline form 1 of N-cyclohexyltryptamine, crystalline form 1 of tryptamine, and crystalline form 1 of N-cyclohexyltryptamine hydrobromide, to compositions containing the same, and to methods of treatment using them.
