CAS 2321-07-5: Fluoresceina
Descrizione:
Fluoresceina, con il numero CAS 2321-07-5, è un composto organico sintetico noto per le sue vivaci proprietà fluorescenti. Si presenta come una polvere verde brillante o un solido cristallino ed è solubile in acqua, alcol e altri solventi organici. Fluoresceina è caratterizzato dalla sua forte fluorescenza sotto luce ultravioletta, rendendolo ampiamente utilizzato come tracciante fluorescente in varie applicazioni, tra cui l'imaging biologico, la tintura e come indicatore di pH. La sua struttura molecolare consiste in un nucleo di xantene, che contribuisce alla sua fluorescenza, e presenta un'alta assorbanza molare, aumentando la sua visibilità nelle soluzioni. Fluoresceina è non tossico a basse concentrazioni, ma è necessario prestare attenzione per evitare esposizioni eccessive. Oltre al suo utilizzo nella ricerca scientifica, è impiegato anche nella diagnostica medica, in particolare in oftalmologia per valutare l'integrità corneale e in angiografia. In generale, Fluoresceina è un composto versatile con una significativa utilità sia in contesti di laboratorio che clinici.

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.Formula:C20H12O5Colore e forma:PowderPeso molecolare:332.31 g/molFluorescein
