| METHYLENEDIPHOSPHONIC ACID Usage And Synthesis |
Chemical Properties | Colourless solid | Uses | Radioactive imaging agent | Uses | Methylenediphosphonic acid is a radioactive compound used for skeletal imaging. MDP has been used as a chelating agent to vary calcium levels in cell culture in a study of caffeine storage in bovine chromaffin cells. | Uses | Methylenediphosphonic acid can be used as a precursor in the synthesis of:
- Mesoporous aluminum organophosphonate in the presence of alkyltrimethylammonium as a surfactant.
- Tetraester of methylenediphosphonic acids which are used as metal ion extractants for actinides in all oxidation states.
| Definition | ChEBI: A 1,1-bis(phosphonic acid) consisting of methane substituted by two phosphonic acid groups. | General Description | MDP (Methylenediphosphonic acid) is a phosphonic analog of ATP. |
