Scandium (III) Triflate ni kichocheo kinachofanya kazi sana, bora, kinachoweza kupona na kinachoweza kutumika tena. Kichocheo chake muhimu kwa acylation ya Friedel-Ufundi, athari za Diels-Alder na athari zingine za kutengeneza kaboni-kaboni. Pia inasababisha kuchochea upolimishaji mkali wa acrylates. 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-aryl-3-butenoates.

Scandium (III) trifluoromethanesulfonate hutumiwa sana kama kichocheo katika hydrothiolation, kuchagua elektroni mbili ya elektroni ya oksijeni na derivatives ya ferrocene na vinylogous fridel-ufundi wa indoles na pyrrole katika maji. Inahusika katika nyongeza ya mukaiyama aldol na inachochea uporaji mkali wa acrylates. Inafanya kama kichocheo cha asidi ya Lewis na hutumika katika muundo wa ng'ombe kupitia njia ya kiberiti iliyoimarishwa.
