Silver trifluoromethanesulfonate (Cat No.:R029139) is a silver salt of trifluoromethanesulfonic acid (triflic acid), with the molecular formula CF₃SO₃Ag. It appears as a white to off-white crystalline solid and is highly soluble in organic solvents. AgOTf is commonly used in organic and organometallic chemistry as a Lewis acid catalyst, halide scavenger, and for promoting various coupling and cyclization reactions. Its strong electrophilic nature and non-coordinating triflate anion make it useful in selective transformations. The compound should be handled with care, avoiding moisture and light, and using appropriate protective measures.
