General description

1-Dimethylamino-2-propanol (1DMA2P, DMAPH), a tertiary amine, is a dimethylamino-alcohol having high boiling point. It is a potent protector against mechlorethamine cytotoxicity and inhibitor of choline uptake. Kinetics of homogeneous reaction of carbon dioxide (CO2) with 1-dimethylamino-2-propanol in water has been investigated using stopped-flow technique.

Application

1-Dimethylamino-2-propanol solution may be used in the synthesis of the following:
  • novel unsymmetrical 2,3,9,10,16,17,23-heptakis(alkoxyl)-24-mono(dimethylaminoalkoxyl)phthalocyanine compounds
  • homoleptic nickel(II) aminoalkoxide
  • Adduct with cobalt(II) 2,4-pentanedionate (acac)
