Nyob rau hauv cov organic chemistry, triflate, tseem paub los ntawm lub npe systematic trifluoromethanesulfonate, yog ib pawg ua haujlwm nrog cov qauv CF₃SO₃−. Pawg triflate feem ntau yog sawv cev los ntawm −OTf, as opposed to −Tf (triflyl). Piv txwv li, n-butyl triflate tuaj yeem sau ua CH₃CH₂CH₂CH₂OTf.

Lanthanum trifluoromethanesulfonate yog siv rau hauv Aldol cov tshuaj tiv thaiv ntawm silyl enol ethers nrog aldehydes. Nws yog ib qho txiaj ntsig zoo rau cov tshuaj tiv thaiv Baylis-Hillman. Nws kuj catalyzes Michael ntxiv rau methyl vinyl ketone hauv dej.
Lewis acid uas ua rau cov dej tsis zoo siv hauv Aldol cov tshuaj tiv thaiv ntawm silyl enol ethers nrog aldehydes.
