The CLP Regulation ensures that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union through classification and labelling of chemicals. n. A glacial or syrupy viscous liquid, H4P2O7, used as a catalyst and in organic chemical manufacture. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. More information about CAS and the CAS registry can be found here. Computed by OEChem 2.1.5 (PubChem release 2019.06.18) 2.2 Molecular Formula H4O7P2 Computed by PubChem 2.1 (PubChem release 2019.06.18) Pyrophosphoric acid is colorless, odorless, hygroscopic, syrupy liquid or crystal form.

More information about the EC Inventory can be found here. In hypophosphoric acid the phosphorus atoms are identical and joined directly with a P−P bond. Pyrophosphoric acid is from phosphoric acid by dehydration. Pyrophosphates are salts of pyrophosphoric acid and metaphosphates are salts of metaphosphoric acid. The IUPAC name of Pyrophosphoric acid is phosphono dihydrogen phosphate. The ratio of these P2O5 contents provides a relative phosphoric acid content, which for pyrophosphoric acid is 79.8%/72.4% = 110%. The compound is not particularly useful, except that it is a component of polyphosphoric acid and the conjugate acid of the pyrophosphate anion. In that case, the ATP (Adaptation to Technical Progress) number is displayed. Phosphine; Trihydrogen Phosphide Close Find out more on how we use cookies.
