Description
General
description
Phosphoric acid (H3PO4),
also known as orthophosphoric acid, is an inorganic acid. It has a wide range
of industrial applications such as an intermediate to produce animal feedstock,
to prepare stock solutions for workup procedures and to treat the metal
surfaces for better adhesion of paint and resin coatings.[6][7] In
the food industry it is used as a preservative, an acidulant and flavor
enhancer.[7]
Sigma Life Science is committed

Application
Phosphoric acid may be employed
as standard for the determination of phosphorus-31 nuclear magnetic resonance (31P
NMR) chemical shifts of the common phospholipids.[1] It
may be employed in the following studies:
• As external standard for the analysis of lipid composition of human
white matter by 31P NMR spectroscopy.[3]
• As external standard during the acid-labile phosphorylation of histone
H4 by 31P NMR spectroscopy.[2]
• As reference standard to investigate the surface species present on
silica/alumina-supported sodium phosphates by pre- and postreaction MAS31P-NMR
and FTIR spectroscopies.[4]
• As catalyst in the vapor-phase Fries rearrangement of phenylacetate at
623K over a series of surface modified and unmodified ZSM-5.[5]
• As an eco-friendly reagent for the removal of protecting groups like tert-butyl
carbamates, tert-butyl esters and tert-butyl ethers.[8]
