2,4,6-Triphenylpyrylium tetrafluoroborate is used as a sensitizer to carry out the photo oxidation of cathecol. It is also used in the preparation of three N-alkylpyridinium photosensitizers by reacting with (1R,2S)-(-)-norephedrine, (S)-(+)-2-(aminomethyl)pyrrolidine and (R)-(-)-1-cyclohexylethylamine.

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.
