Aminomethyl propanol is an organic compound with the formula H2NC(CH3)2CH2OH. It is colorless liquid that is classified as an alkanolamine. It is a useful buffer and a precursor to numerous other organic compounds.[1]


Aminomethyl propanol can be produced by the hydrogenation of 2-aminoisobutyric acid or its esters.


Aminomethyl propanol is soluble in water[2][3] and about the same density as water.[2]


Aminomethyl propanol is used for the preparation of buffer solutions.[2] It is a component of the drugs ambuphylline and pamabrom. It is also used in cosmetics.[1]

It is a precursor to oxazolines via its reaction with acyl chlorides.[4] Via sulfation of the alcohol, the compound is also a precursor to 2,2-dimethylaziridine.[5]
