Methylene diphosphonic acid

Medronic acid is a 1,1-bis(phosphonic acid) consisting of methane substituted by two phosphonic acid groups. Among its listed roles, it functions as a bone density conservation agent and a chelator. Medronic Acid is a methylene-substituted bisphosphonate. Medronic acid has affinity for and adheres to the surface of hydroxyapatite crystals in the bone matrix. This agent accumulates at sites of osteoid mineralization and can be used, complexed with radioisotopes including technetium 99m, in bone imaging. The directory classifies it as a commercial API with a synthetic source/manufacturing origin. Other names for this substance include Acide medronique and Acido medronico. Its PubChem CID is 16124.
