Polyphosphoric acid, ca 84% (as phosphorus pentoxide), Thermo Scientific Chemicals

Description

Polyphosphoric acid is used as a dehydrating agent, cyclizing agent, acylating agent, analytical reagent and as a ring closing reagent. It is used in the production of phosphate esters, acid phosphates and pharmaceuticals. It is involved in metal treatment and as an asphalt and a bitumen additive. Furthermore, it is employed for the determination of tryptophan and used a reagent for the alkylation and acylation reactions of aromatic and alkenic compounds.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
