Ethylenediaminetetraacetic Acid Dianhydride (A-EDTA) is used as a reagent in the synthesis of a new class of polymer, poly-2.6-piperazinedione. A-EDTA is also used in the synthesis of EDTA functionalized polyacrylnitriles (PANs) by direct reaction with amine and hydroxyl functionalized polyacrylnitrile.
Ethylenediaminetetraacetic dianhydride (EDTAD) is a ramification of ethylenediaminetetraacetate (EDTA), which consists of two anhydride groups that can react with the hydroxyl and the amino groups. It is a biodegradable compound that is used as a chelating agent.
