Chemical Propertieslight beige powder

UsesEtidronate (Didronel) is a human protein tyrosine phosphatase inhibitor with IC50 of 0.2 μM.

DefinitionChEBI: A 1,1-bis(phosphonic acid) that is (ethane-1,1-diyl)bis(phosphonic acid) having a hydroxy substituent at the 1-position. It inhibits the formation, growth, and dissolution of hydroxyapatite crystals by chemisorption to calcium phosphate surfaces.

Brand nameDidronel (Millot Laboratories, France); Didronel (Procter & Gamble).
