Application: | Iminodiacetic acid (IDA) can be used as a tridentate ligand to chelate metal ions. Some of the common applications of IDA include: • Synthesis of N-methyliminodiacetic acid (MIDA), which is an essential precursor for the synthesis of highly versatile MIDA boronates for cross coupling reactions. • Synthesis of metal complexes of iminodiacetic acid with a radionuclide, especially 99mTc are as radiotracers for cholescintigraphy scans and for radiopharmaceutical applications. • Synthesis of lanthanide hybrid frameworks via self-assembly of lanthanide ions (Ln3+) with iminodiacetic acid under hydrothermal conditions. • Preparation of a thermosensitive macroporous protein-imprinted hydrogel for the recognition of protein by metal coordinate interaction. • Synthesis of IDA functionalized styrene-divinyl benzene co-polymeric beads for the removal of heavy metal ions like Cd(II), Cr(VI), Ni(II) and Pb(II) from their aqueous solutions. |
