Scandium triflate

Scandium triflate (CAS 144026-79-9, EC 629-306-8) is an inorganic scandium salt formed from scandium and triflic acid, also referenced as Sc(OTf)3 or scandium(III) triflate. It carries no assigned E-code. The compound is registered under REACH and classified within HS code 28469099 covering rare earth metal compounds.

In pharmaceutical and polymer manufacturing, scandium triflate functions as a Lewis acid catalyst, activating electrophilic reactions such as Friedel-Crafts acylations and Diels-Alder cycloadditions under mild conditions. In textile and leather processing, it contributes to antimicrobial preservation and flame retardancy by coordinating with substrate functional groups to disrupt microbial activity and alter combustion pathways.

Scandium triflate is supplied as a white powder in technical and research grades, compliant with REACH registration requirements. Procurement quantities are available from laboratory scale through bulk industrial packaging. Buyers should confirm grade specifications and documentation, including SDS and certificate of analysis, prior to ordering.
