2,4,5-7-Tetrabromofluorescein disodium salt

Description:
2,4,5,7-Tetrabromofluorescein disodium salt is a synthetic organic compound known for its vibrant fluorescent properties, making it useful in various applications, particularly in biological and chemical assays. This compound is a derivative of fluorescein, characterized by the presence of four bromine atoms at specific positions on the aromatic rings, which significantly alters its optical properties. It typically appears as a dark red to brown powder and is soluble in water, allowing for easy incorporation into aqueous solutions. The disodium salt form enhances its solubility and stability in biological environments. Its fluorescence is sensitive to pH changes, making it valuable as a pH indicator and in fluorescence microscopy. Additionally, due to its brominated structure, it may exhibit higher stability against photodegradation compared to non-brominated fluorescein derivatives. However, caution is advised when handling this compound, as brominated compounds can have environmental and health implications. Overall, 2,4,5,7-Tetrabromofluorescein disodium salt is a versatile reagent in scientific research and analytical chemistry.
