General description

Phosphoric acid solution is widely used NMR reference standard.

Application

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.

Features and Benefits

31P sensitivity

Packaging

Coaxial 4.2 mm O.D. x 8 in. tube (equivalent to Wilmad WGS-5BL) designed to be used inside a 5 mm x 7 in. NMR tube.
