Application
Ytterbium(III) trifluoromethanesulfonate hydrate is used to promote glycosidation of glycosyl fluorides and as a catalyst in the preparation of pyridine and quinoline derivatives.
Ytterbium trifluoromethanesulfonate has water resistance and is often used to catalyze various organic synthesis reactions. The purity is usually ≥98%, the appearance is white crystal, and the storage condition is 2-8℃23. It exhibits strong acidity in aqueous solutions and is often used in organic synthesis reactions that require strong acid catalysis
