Several methods exist for the preparation of phosphonic acids and their salts. From phosphonic acid Most processes begin with phosphorous acid (aka phosphonic acid, H3PO3), exploiting its reactive P−H bond. Phosphonic acid can be alkylated under Mannich conditions to give aminomethylated phosphonates, … See more In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR)2 groups (where R = alkyl, aryl, or just hydrogen). Phosphonic acids, typically handled as salts, are generally See more Hydrolysis Phosphonate esters are generally susceptible to hydrolysis under both acidic and basic … See more Bisphosphonates 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 … See more In 1998 the consumption of phosphonates was 56,000 tons worldwide – 40,000 tons in the US, 15,000 tons in Europe and less than 800 tons in Japan. The demand of phosphonates grows steadily at 3% annually. Metal chelants See more Phosphonates feature tetrahedral phosphorus centers. They are structurally closely related to (and often prepared from) phosphorous acid. Phosphonate salts … See more Phosphonates are one of the three sources of phosphate intake in biological cells. The other two are inorganic phosphate and organophosphates. The naturally occurring phosphonate 2-aminoethylphosphonic acid was first identified in 1959 in … See more In medicine, phosphonates and bisphosphonates are commonly used as inhibitors of enzymes which utilize phosphates and diphosphates as substrates.

WebEtidronic 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.
