[Chemical Properties]

white or yellowish crystalline powder
[Uses]

Iminodiacetic acid can be used:
  • In the preparation of iminodiacetic acid (IDA)-type adsorbent for protein purification.
  • As a catalyst along with iron (FeCl3) complexes for methyl methacrylate (MMA) polymerization.
  • In the preparation of chelating resins with glycidyl methacrylate for the selective removal and recovery of metal ions from industrial waste water.
  • As a reagent for the preparation of pinene-derived iminodiacetic acid (PIDA), which is in turn used as a ligand for the synthesis of diastereoselective oxiranyl C(sp3) boronates from the corresponding olefins.
  • In the surface functionalization of multi-walled carbon nanotubes (MWCNTs) which is further utilized as a sorbent for the separation of heavy metal ions.

[Definition]

ChEBI: An amino dicarboxylic acid that is glycine in which one of the hydrogens attached to the nitrogen is substituted by a carboxymethyl group.
[Purification Methods]

Crystallise 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]. [Laberek & Martell J Am Chem Soc 74 5052 1952, Beilstein 4 III 2428, 4 IV 1176.]
