Triphenyl phosphite, 97%, Thermo Scientific Chemicals

Description

Used to convert alcohols to alkyl halides, as a peptide coupling agent, and, in combination with ozone, as a low-temperature source of singlet oxygen, and ligand for metal-catalyzed reactions. Also used as reagent in the preparation of mixed valent nickel diphosphine dithiolate bridged iron carbonyl phosphine complexes as models of [NiFe]-hydrogenase active site.

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.
