CAS 17372-87-1
:Eosina
Descrição:
Eosina, com o número CAS 17372-87-1, é um corante sintético pertencente à classe dos corantes xantênicos. É utilizado principalmente como um corante biológico em histologia e citologia, permitindo a visualização de estruturas celulares sob um microscópio. Eosina é caracterizado por sua vibrante cor vermelha a rosa, que resulta de seu sistema de ligações duplas conjugadas que permite uma eficaz absorção de luz. O corante é solúvel em água e álcool, tornando-o versátil para várias aplicações. Eosina é frequentemente utilizado em combinação com hematoxilina em protocolos de coloração, onde fornece contraste aos núcleos corados de azul, destacando o citoplasma e outros componentes celulares. Além disso, Eosina exibe propriedades de fluorescência, que podem ser utilizadas em microscopia de fluorescência. É importante manusear Eosina com cuidado, pois pode causar irritação ao contato com a pele ou os olhos. No geral, Eosina é uma ferramenta valiosa na pesquisa biológica e no diagnóstico, auxiliando no estudo da morfologia dos tecidos e das características celulares.
