Maombi
Ytterbium (III) trifluoromethanesulfonate hydrate hutumiwa kukuza glycosidation ya glycosyl fluorides na kama kichocheo katika utayarishaji wa pyridine na derivatives ya quinoline.
Ytterbium trifluoromethanesulfonate ina upinzani wa maji na mara nyingi hutumiwa kuchochea athari tofauti za awali za kikaboni. Usafi kawaida ni ≥98%, muonekano ni kioo nyeupe, na hali ya kuhifadhi ni 2-8 ℃23. Inaonyesha asidi kali katika suluhisho la maji na mara nyingi hutumiwa katika athari za awali za kikaboni ambazo zinahitaji nguvu ya asidi
