DTPA

Pentetic acid or Diethylene tri amine Penta acetic acid (DTPA) is an aminopoly carboxylic acid consisting of a diethylene tri amine back bone  with five carboxymethyl group. The molecule can be viewed as an expanded version of EDTA and is used similarly. It is a white solid with limited solubility in water.

Like the more common EDTA, DTPA is predominantly used for sequestering metal ions that otherwise decompose hydrogen peroxide, which is used to bleach pulp in paper making.

Its chelating properties are useful in deactivating calcium and magnesium ions in hair products. DTPA is used in over 150 cosmetic products. Additionally, DTPA is used in MRI contrasting agents. DTPA improves MRI images by forming a complex with a gadolinium ion, which alters the properties of nearby water molecules.

DTPA has been considered for treatment of radioactive materials such as plutonium, americium, and other actinides.

 In theory, these complexes are more apt to be eliminated in urine. It is normally administered as the calcium or zinc salt, since these ions are readily displaced by more highly charged cations. DTPA forms complexes with thorium(IV), uranium(IV), neptunium(IV), and cerium(III/IV).

DTPA is also used as a chelate for aquarium plant fertilizer, specifically iron, an essential micronutrient typically needed in substantial quantities by all plants.

Chelates are dissolved organic substances that bind to metals and prevent them from forming larger molecules through oxidation.

FeDTPA is often sold under the name iron chelate 10% or 11% when used for the purpose of aquarium plant fertilization. Iron typically found in the aquarium water column has been converted into the ferric state (Fe³⁺) since it is in the presence of dissolved oxygen.

However plants require iron in the ferrous state (Fe²⁺), therefore additional energy must be expended in order to extract the ferric iron from the water column and convert it to the ferrous form.

chelate iron fertilizer DTPA that the iron is kept in the ferrous state (Fe²⁺) over time it can be utilized by aquatic plants without expending valuable energy.

A High grade of DTPA Penta sodium salt is manufactured by SHIV CHEM INDUSTRIES. It is also known as Diethylene tri amine penta acetic acid penta sodium salt  or Penta sodium  DTPA.It is a sequestering agent or Chelating agent. It is synthetic of amino acid. It is pale yellow liquid  highly soluble in water. DTPA pentasodium salt ismanufactured by reaction of DTPA acid, DM water and Caustic flakes at higher  temperature. DTPA and Its derivatives are used to remove dissolve metallic impurities.
