Product Description

Product name:   DTPA
Classification:    Diethylenetriaminepentaacetic acid
CAS No.:           67-43-6
Other Names:    Pentetic acid
MF:                    C14H23O10N3
Purity:                ≥99.0%

    DTPA is a white crystal powder. The conjugate base of DTPA has a high affinity for metal cations. Thus, the penta-anion DTPA5− is potentially an octadentate ligand assuming that each nitrogen centre and each COO−-group counts as a centre for coordination. The formation constants for its complexes are about 100 greater than those for EDTA.
    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.

ApplicationAs a high efficiency chelating agent, it is used in color inhibitor, papermaking industry, water softener, textile auxiliaries, chelating titrant, color photography and food industry.
