CAS 2321-07-5
:Fluoresceína
Descripción:
Fluoresceína, con el número CAS 2321-07-5, es un compuesto orgánico sintético conocido por sus vibrantes propiedades fluorescentes. Aparece como un polvo verde brillante o un sólido cristalino y es soluble en agua, alcohol y otros disolventes orgánicos. Fluoresceína se caracteriza por su fuerte fluorescencia bajo luz ultravioleta, lo que lo hace ampliamente utilizado como un trazador fluorescente en diversas aplicaciones, incluyendo la imagenología biológica, el teñido y como indicador de pH. Su estructura molecular consiste en un núcleo de xanteno, que contribuye a su fluorescencia, y exhibe una alta absorbancia molar, lo que mejora su visibilidad en soluciones. Fluoresceína es no tóxico a bajas concentraciones, pero se debe tener cuidado para evitar la exposición excesiva. Además de su uso en la investigación científica, también se emplea en diagnósticos médicos, particularmente en oftalmología para evaluar la integridad corneal y en angiografía. En general, Fluoresceína es un compuesto versátil con una utilidad significativa tanto en entornos de laboratorio como clínicos.

CAS:<p>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.<br>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.</p>Fórmula:C20H12O5Forma y color:PowderPeso molecular:332.31 g/molRef: 3D-FF23342
