2-Amino-2-methyl-1,3-propanediol Usage And Synthesis

Chemical Propertieswhite powder
UsesEmulsifying agent (in soap form) for oils, fats, and waxes; absorbent for acidic gases; organic synthesis; cosmetics.
DefinitionChEBI: An aminodiol that is propane-1,3-diol substituted ny an amino and a methyl group at position 2.
Purification MethodsCrystallise the diol three times from MeOH, dry in a stream of dry N2 at room temperature, then in a vacuum oven at 55o. Store it over CaCl2 [Hetzer & Bates J Phys Chem 66 308 1962]. [Beilstein 4 IV 1881.]
