Fluka Phosphoric acid ACS reagent, =85 wt. % in H2O

Not yet rated

Phosphoric acid (H3PO4) is useful in industry for treating the metal surfaces to obtain better adhesion of paint and resin coatings.

Synonyms: Orthophosphoric acid

Molecular Formula: H3O4P

Molecular Weight: 98.0

Linear Structural Formula: H3PO4

MDL Number: MFCD00011340

Purity: >=85% H3PO4 basis (by NaOH, titration)

Melting Point: ~40 C (lit.)

Density: 1.685 g/mL at 25 C (lit.)

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. 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 MAS31P-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.

Other Notes: Concentrated phosphoric acid is approx. 85% H3PO4 (aqueous).
