Scandium (III) Triflate waa mid aad u firfircoon, hufan, oo dib loo soo celin karo oo dib loo isticmaali karo oo ah cunsuriyada filaadka. Waxay u tahay wax muhiim ah oo muhiim u ah 'fretic-crather-charting', jawaab-celinta alls-alls-alls-ka iyo fal-celinta kale ee kaarboonka-kaarboon-kaarboon-kaarboon-kaarboon-ka-qaade. Waxa kale oo ay si joogto ah u xajisaa sifeeysinta sicirka sicirka xagjirka ah ee acrylades. Scandium(III) triflate complex of (4′S,5′S)-2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine has been employed as catalyst for the asymmetric Friedel-Crafts reaction between substituted indoles and methyl (E) -2-oxo-4-arlyl-3-buntotes.

Scandium (III) Trifleoromethenansulethonate ayaa si weyn loogu isticmaalaa sidii biyo-daad-u-dhigga, laba-elekrous laba-elek leh oo ah oksijiin ka samaysan astaamaha loo yaqaan 'fronylogen' ee wax lagu qoro iyo pyrrole biyo. Waxay ku lug leedahay isku-darka aldol ee Mukaiyama iyo si dhib yar oo ay ku celceliyaan polymoodka xagjirka ah ee acrylades. Waxay u dhaqmeysaa sidii wax ku dhex-dhexaadin ah oo lewis ah oo loo isticmaalo isku-darka bullflone bullvalone iyada oo loo marayo sulfur oo xasilisay.
