4-Azido-2,3,5,6-tetrafluorobenzoic Acid

4-Azido-2,3,5,6-tetrafluorobenzoic Acid (N3-TFBA) is a click chemistry reagent containing an azide group. 4-Azido-2,3,5,6-tetrafluorobenzoic Acid is a complex with FAM-labeled DNA probe. 4-Azido-2,3,5,6-tetrafluorobenzoic Acid can be used as versatile photoaffinity labeling agents to probe biological receptors. It contains an azide group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing alkyne groups. It can also undergo ring strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.
