Description and Uses

3-Methylamino-1,2-propanediol (MAPD) is a clear liquid with the chemical formula C₄H₁₁NO₂. It can be synthesized from allylamine and alkanolamine via a thermal process. It reacts with chloride to form methyl chloroacetate, which can then be converted into 3-methylamino-1,2-propanediol by reaction with methanol. The production process for this substance has been shown to generate low levels of hazardous substances such as polycyclic aromatic hydrocarbons (PAHs) and dioxins.

3-Methylamino-1,2-propanediol is a reactive compound that is used in the synthesis of organic acids. It is also used as an intermediate in the manufacture of polyethylene glycols and particle coatings.
