Application

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.

Extracellular inorganic pyrophosphate (PP(i)) is a potent suppressor of physiological calcification in bone and pathological calcification in blood vessels. Ectonucleotide pyrophosphatase/phosphodiesterases (eNPPs) generate PP(i) via the hydrolysis of ATP released into extracellular compartments by poorly understood mechanisms. Here we report
