General description

Iminodiacetic acid is a versatile chelating agent widely used in metal extraction and waste water treatment.

Application

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.
