Tetrabromofluoresceinpotassiumsalt

Description:
Tetrabromofluorescein potassium salt, with the CAS number 56897-54-2, is a synthetic organic compound that belongs to the class of fluorescent dyes. It is characterized by its vibrant fluorescence, which makes it useful in various applications, including biological staining and as a tracer in environmental studies. The compound features a tetrabromofluorescein structure, where bromine atoms are substituted on the fluorescein backbone, enhancing its photophysical properties. As a potassium salt, it is typically soluble in water, allowing for easy application in aqueous environments. The dye exhibits strong absorption in the visible spectrum, particularly in the green region, and emits light in the yellow-green range when excited. Its stability under various conditions and ability to bind to biological molecules make it valuable in microscopy and flow cytometry. However, like many synthetic dyes, it should be handled with care due to potential environmental and health impacts, necessitating appropriate safety measures during use.
