o-Aminophenol-N,N,O-triacetate, known as APTRA, is one of the most well-established ligands for targeting magnesium ions but, like other aminocarboxylate ligands, it binds Ca2+ much more strongly than Mg2+. The synthesis of an O-phosphinate analogue... Read More about Enhanced selectivity for Mg2+ with a phosphinate-based chelate: APDAP versus APTRA.
