Further substitution gives nitrilotriacetic acid, NTA, which is a tetradentate ligand. [3] These compounds can be described as aminopolycarboxylates. Related ligands can be derived from other amino acids other than glycine, notably aspartic acid. Binding of a metal complex by the iminodiacetate anion
Nitrilotriacetonitrile (NTAN) is a precursor for nitrilotriacetic acid (NTA, a biodegradable complexing agent and building block for detergents), for tris(2-aminoethyl)amine (a tripodal tetradentate chelating agent known under the abbreviation tren) and for the epoxy resin crosslinker aminoethylpiperazine.

N-acyl amides are a general class of endogenous fatty acid compounds characterized by a fatty acyl group linked to a primary amine metabolite by an amide bond. Broadly speaking, N-acyl amides fall into several categories: amino acid conjugates (e.g., N-arachidonoyl-glycine), neurotransmitter conjugates (e.g., N-arachidonoyl-serotonin), ethanolamine conjugates (e.g., anandamide), and taurine ...
Various carrier matrices bound to a solid resin support are on the market and these can be subsequently charged with a metal cation. Derivatives of iminodiacetic acid (IDA) and nitrilotriacetic acid (NTA) are most frequently used for this purpose, with differing matrices having certain advantages and disadvantages for various applications.

As biodegradable alternatives from the class of widespread chelating agents, only nitrilotriacetic acid (NTA) is sufficiently biodegradable under certain conditions (which is suspected of being carcinogenic, though) and the chelating active amino acid derivatives β-alaninediacetic acid and methylglycine diacetic acid (Trilon M®).
