Hydroxyethylidene diphosphonic acid complex

WebHEDP (Hydroxyethylidene Diphosphonic acid), together with the calcium ion in particular, reacts with metal ions in the water system to form a hexa-element chelate-forming complex. HEDP (Hydroxyethylidene Diphosphonic acid) therefore has good antiscale and visible threshold effects. Etidronic acid is a bisphosphonate used to strengthen bone, treat osteoporosis, and treat Paget's disease of bone. Bisphosphonates primarily reduce osteoclastic activity, which prevents bone resorption, and thus moves the bone resorption/formation equilibrium toward the formation side and hence makes bone stronger on the long run. Etidronate, unlike other bisphosphonates, also prevents bone cal… Compounds containing 2 geminal phosphonate groups are known as bisphosphonates. They were first synthesized in 1897 by Von Baeyer and Hofmann and now form the basis for an important class of drugs, used to treat osteoporosis and similar diseases. Examples include HEDP (etidronic acid or Didronel), which is prepared from phosphorous acid and acetic anhydride:
