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.

Erythrosin B

CAS: 15905-32-5

Erythrosin B is a fluorescent dye that is used in biological research. It has been shown to have cytotoxic effects on human leukemia cells (HL-60) and cytotoxic effects on human lymphocytes. The toxicities of this compound are dependent on the concentration and the duration of exposure, as well as the type of biological sample. Erythrosin B can be used to detect DNA damage in cells by using an analytical method called matrix effect synchronous fluorescence. This dye appears to be genotoxic in vitro and in vivo, but its long-term toxicity is unknown. Erythrosin B has antimicrobial properties against gram-positive bacteria and fungi, but it does not have any activity against Gram negative bacteria or viruses.
