Indium(III) trifluoromethanesulfonate（Cat No.:R062396）, also known as indium triflate, is a Lewis acidic metal triflate with the formula In(OTf)₃. This water-tolerant catalyst is widely used in organic synthesis for promoting reactions such as Friedel–Crafts acylations, Diels–Alder cycloadditions, and allylation processes. Its strong electrophilicity combined with stability in aqueous and polar media makes it an attractive alternative to traditional acid catalysts. The triflate groups enhance solubility and reactivity without introducing nucleophilic interference. Indium(III) triflate is also applied in green chemistry protocols and complex molecule construction due to its efficiency and mild reaction conditions.
