Beschreibung

Allgemeine Beschreibung

Phosphoric acid solution is widely used NMR reference standard.

Anwendung

Phosphoric acid may be employed in the following studies:

• As standard for the determination of phosphorus-31 nuclear magnetic resonance (³¹P NMR) chemical shifts of the common phospholipids.
• As external standard for the analysis of lipid composition of human white matter by ³¹P NMR spectroscopy.
• As external standard during the acid-labile phosphorylation of histone H4 by ³¹P NMR spectroscopy.
• As reference standard to investigate the surface species present on silica/alumina-supported sodium phosphates by pre- and postreaction MAS³¹P-NMR and FTIR spectroscopies.
