Medical definition of phosphonic acid: any of a series of dibasic organic acids RPO(OH)2 that are obtainable from some phosphines by oxidation. CAS Number: 205638-90-0. Phosphorous acid dissociates to form the phosphonate ion (HPO 3 2-), also called phosphite. It acts as a rust converter on direct application to rusted iron, steel, and other metal surfaces. Phosphonic acid natural products possess several traits that make them ideal candidates for large-scale genome mining. 3.1 CAS No and Grouping information Phosphonates are multifunctional acids, which structurally have the phosphonic acid … … Phosphonic acids are well known and effective chelating agents. When this happens, … 2. Data for this HERA assessment have been taken wherever possible from the SIARs. The realisation that phosphonic acid derivatives could, under certain circumstances, react with alcohols to give phosphonate mono-esters was made in 1973 at the Stanford Research Institute. This behavior is associated to the fact that the trisphosphonic acid sodium salt was already solvated at the solid state. Phosphonic acid EC Number: 237-066-7 EC Name: Phosphonic acid CAS Number: 13598-36-2 Molecular formula: H3O3P IUPAC Name: phosphonic acid . HEDP is an organic phosphonic acid that can be used in many fields.HEDP and its sodium salts (HEDP Na, HEDP Na 2, HEDP Na 4) are called all-purpose organic phosphine products. After this treatment, the black ferric phosphate coating can be easily scrubbed off, revealing the underlying fresh metal surface. It converts reddish-brown iron, that is, ferric oxide, to black-colored ferric phosphate. What is phosphoric acid? Phosphonates are not volatile and are poorly soluble in organic solvents. Phosphonates or Phosphonic acids are organic compounds containing one or more C-PO(OH) 2 or C-PO(OR) 2 (with R=alkyl, aryl) groups.

The former is a diprotic acid (readily ionizes two protons), but the latter is a triprotic acid (readily ionizes three protons). Once a familiar sight on fountain menus, the phosphate may have drifted out of the spotlight due to its primary ingredient.
