Structural formula: {0} (CAS {1})

Etidronic acid is 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. It has a role as an antineoplastic agent, a chelator and a bone density conservation agent. It is a conjugate acid of an etidronic acid(2-).
