Triethylenetetramine presents as a pale yellow viscous fluid with powerful alkaline properties and medium viscosity, featuring an odor similar to ammonia. It has lower volatility compared with diethylenetriamine, while other characteristics are alike. This substance dissolves in water and ethanol, and is sparingly soluble in diethyl ether. Its water solution shows strong alkalinity.
