high quality Ferric ammonium DTPA cas no 85959-68-8
Product introduction
Product name: DTPA-Fe An
English name: Ferric ammonium DTPA
CAS-No: 85959-68-8
Molecular formula: C14H18N3O10Fe(NH4)2
Molecular weight: 480.2
Properties: reddish brown sticky liquid, non-toxic, dissolved in water and acid, lightly soluble in ethyl alcohol
As a chelating agent, DTPA wraps around a metal ion by forming up to eight bonds. Transition metals, however, usually form less than eight coordination bonds. So, after forming a complex with a metal, DTPA still has the ability to bind to other reagents, as is shown by its derivative pendetide. For example, in its complex with copper(II), DTPA binds in a hexadentate manner utilizing the three amine centres and three of the five carboxylates.
