Product details

Ethylene Diamine Tetra (Methylene Phosphonic Acid)

EDTMPA (Solid)



 




Synonyms:


 



EDTMPA;EDTMP;EDTMP(A);Ethylene Diamine Tetra (Methylene Phosphonic Acid); EDTPO



 



CAS No. 1429-50-1



Molecular Formula: C6H20 N2O12P4 Molecular weight: 436.13



Structural Formula:







 




Properties:


 



At room temperature, EDTMPA is a white crystal powder with a melting point of 215-217°C. It is difficult to dissolve in water and very slightly soluble in ammonia.Strong metal ion chelating properties of EDTMPA are demonstrated by its higher chelating constant with the cuprum ion than that of EDTA.



 



The ability of EDTMPA to chelate metal ions is quite strong. All chelating drugs, including EDTA, have a complex constant with Cu that is the highest.It may be used as a detergent in semiconductor chips to manufacture integrated circuits, as a carrier for radioactive elements in the medical industry, and as a tool for therapy and inspection. EDTMPA is a kind of high-purity grade reagent. Since EDTMPA has a far higher chelating capability than EDTA and DTPA, it may nearly always be used in place of EDTA as a chelating agent.

FAQ:


 



What is EDTMPA (Solid)?



Ethylene Diamine Tetra (Methylene Phosphonic Acid) EDTMPA (Solid) is a solid, white phosphorus-based compound used as a chelating agent and corrosion inhibitor. It is insoluble in water and has a molecular weight of 376.37 g/mol.



 



What are the uses of EDTMPA (Solid)?



EDTMPA (Solid) is a chelating agent in water treatment and boiler systems. It is also a corrosion inhibitor in metal working fluids, cooling tower waters, and paper mill systems.



 



How does EDTMPA (Solid) work?



EDTMPA (Solid) forms complexes with metal ions in solution, preventing the metal ions from interacting with other molecules. This inhibits corrosion and scale formation and helps to keep boiler and cooling tower waters clean.



 



What are the safety concerns associated with EDTMPA (Solid)?



EDTMPA (Solid) is considered a low-toxicity compound and is not expected to harm human health at recommended use levels. However, it should be handled cautiously as it can cause skin and eye irritation.



 



Where can I buy EDTMPA (Solid)?



EDTMPA (Solid) is available from chemical supply companies or online retailers， Example: vcycletech
