2,2,6,6-Tetramethylpiperidine or TMP or HTMP is an organic compound of the amine class. In appearance, it is a colorless liquid and has a "fishy", amine-like odor. This amine is used in chemistry as a hindered base (hindered amine) because it can dissolve in organic solvents unlike inorganic bases such as potassium hydroxide.
