Scandium triflate

Scandium triflate (CAS 144026-79-9), also known as scandium trifluoromethanesulfonate, is a rare earth metal salt valued primarily as a Lewis acid catalyst. It activates a broad range of organic reactions under mild conditions. Unlike many metal catalysts, it retains activity in aqueous media. This property directly reduces solvent costs and waste in manufacturing processes, making it a sustainable choice for modern chemical production facilities.

In pharmaceutical synthesis, this compound catalyzes Friedel-Crafts alkylations, Diels-Alder cycloadditions, and Mannich reactions. It enables efficient construction of complex intermediates without requiring anhydrous conditions. Polymer manufacturers use it to initiate ring-opening polymerizations and controlled cationic processes. This allows for precise control over molecular weight distribution in the production of specialty plastics and resins.

In textile and paper processing, it functions as a catalyst for esterification and crosslinking treatments. These applications improve fiber durability and surface performance for high-end industrial materials. Its application in flame retardant formulation development is emerging. It acts as a catalyst in the synthesis of phosphorus- or halogen-based retardant compounds used in various safety-critical industries.

The product is supplied as a white to off-white crystalline powder. It is available in research quantities through to multi-kilogram commercial lots, with purity grades typically ranging from 95% to 99%+. High-purity grades suited to pharmaceutical and fine chemical synthesis are the most commercially prevalent offerings. These materials meet rigorous internal quality standards for consistency and performance in sensitive reactions.
