CAS 15905-32-5: 2′,4′,5′,7′-Tetraiodofluorescein

Description: 2′,4′,5′,7′-Tetraiodofluorescein, with the CAS number 15905-32-5, is a synthetic organic compound belonging to the fluorescein family, characterized by its intense fluorescence. This compound features a xanthene core with four iodine atoms substituted at the 2′, 4′, 5′, and 7′ positions, which significantly alters its optical properties compared to non-iodinated fluorescein derivatives. The presence of iodine enhances its lipophilicity and can affect its solubility in various solvents. Tetraiodofluorescein is primarily used as a fluorescent dye in biological and chemical applications, including microscopy and flow cytometry, due to its high quantum yield and stability under light exposure. Additionally, it can serve as a tracer in environmental studies and has potential applications in photodynamic therapy. Its chemical structure contributes to its unique spectral properties, making it valuable in research and diagnostic fields. However, handling should be done with care, considering potential toxicity associated with halogenated compounds.
