Aminomethyl propanol (AMP) 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.[2]

Aminomethyl propanol is typically sold as a solution of the material in water, for which different concentrations are available.

Synthesis[edit]

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

Properties[edit]

Aminomethyl propanol is soluble in water[3][4] and about the same density as water.[3]

Uses[edit]

Aminomethyl propanol is used for the preparation of buffer solutions.[3] It is a component of the drugs ambuphylline and pamabrom. It is also used in cosmetics.[2]

It is a precursor to oxazolines via its reaction with acyl chlorides.[5] Via sulfation of the alcohol, the compound is also a precursor to 2,2-dimethylaziridine.[6]

Aminomethyl propanol is used as an intermediate the synthesis of fepradinol, isobucaine, and radafaxine.[citation needed]
