CAS 2321-07-5: Fluorescéine
Description :
Fluorescéine, avec le numéro CAS 2321-07-5, est un composé organique synthétique connu pour ses propriétés fluorescentes vibrantes. Il se présente sous forme de poudre verte brillante ou de solide cristallin et est soluble dans l'eau, l'alcool et d'autres solvants organiques. Fluorescéine se caractérise par sa forte fluorescence sous lumière ultraviolette, ce qui le rend largement utilisé comme traceur fluorescent dans diverses applications, y compris l'imagerie biologique, la teinture et comme indicateur de pH. Sa structure moléculaire se compose d'un noyau de xanthène, qui contribue à sa fluorescence, et il présente une forte absorptivité molaire, améliorant sa visibilité dans les solutions. Fluorescéine est non toxique à faibles concentrations, mais il convient de faire attention à éviter une exposition excessive. En plus de son utilisation dans la recherche scientifique, il est également utilisé dans le diagnostic médical, en particulier en ophtalmologie pour évaluer l'intégrité cornéenne et en angiographie. Dans l'ensemble, Fluorescéine est un composé polyvalent avec une utilité significative tant dans les laboratoires que dans les milieux cliniques.

CAS :Fluorescein is a fluorescent molecule often used in in vitro assays, immunohistochemistry, microscopy, and clinical analytics. Fluorescein is not a natural product and was first synthesized in 1871 by Adolf von Baeyer, a later Nobel-prize winner for his work on organic dyes. Fluorescein has an absorption maximum of 494 nm and an emission maximum of 512 nm; these values can however slightly change depending on the solution medium. Fluorescein is used clinically in ophthalmology to assess the blood flow in the eye blood vessels and to detect eye injuries such as foreign bodies and possible abrasions. Interestingly, fluorescein has been found to possess peroxidase activity under certain conditions.Formule :C20H12O5Couleur et forme :PowderMasse moléculaire :332.31 g/molFluorescein
