Product Description

Phosphoric acid

ACS reagent, 85 wt. % in H2O

Synonym: Orthophosphoric acid


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. In the food industry it is used as a preservative, an acidulant and flavor enhancer.

Sigma Life Science is committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. 


Phosphoric acid may be employed as standard for the determination of phosphorus-31 nuclear magnetic resonance (31P NMR) chemical shifts of the common phospholipids.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.
 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 MAS
P-NMR and FTIR spectroscopies.
 As catalyst in the vapor-phase Fries rearrangement of phenylacetate at 623K over a series of surface modified and unmodified ZSM-5.
 As an eco-friendly reagent for the removal of protecting groups like tert-butyl carbamates, tert-butyl esters and tert-butyl ethers.
