Azide derivative of red fluorescent dye TR (Texas Red, sulforhodamine 101 acid chloride) for click chemistry conjugation with terminal alkynes via a copper-catalyzed click reaction or strained cyclooctynes via a copper-free click reaction. TR is a red-fluorescent dye used for cell staining, fluorescence microscopy applications, and cell sorting with fluorescent-activated cell sorting machines. Texas Red is also commonly used in molecular biology, mainly quantitative RT-PCR and cellular assays.
