Iminodiacetic acid Usage And Synthesis
  • Chemical Propertieswhite or yellowish crystalline powder
  • DefinitionChEBI: An amino dicarboxylic acid that is glycine in which one of the hydrogens attached to the nitrogen is substituted by a carboxymethyl group.
  • Purification MethodsCrystallise the acid several times from water. The N-Methyl derivative m 215o is purified by dissolving it in an equal weight of warm H2O and adding 3 volumes of MeOH [Kiematsu et al. Org Synth Coll Vol II 397 1943].
