METHYLENEDIPHOSPHONIC ACID Chemical Properties,Usage,Production

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.
