Colourless solid | [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.
| [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]
