CAS 6226-79-5: Ponceau S
Descripción:
Ponceau S, con el número CAS 6226-79-5, es un colorante azoico sintético comúnmente utilizado en diversas aplicaciones, incluyendo coloración de alimentos, tinción biológica y como indicador de pH. Se caracteriza por su brillante tono rojo, que se atribuye a la presencia de grupos azo (-N=N-). Ponceau S es soluble en agua, lo que le permite disolverse fácilmente en soluciones acuosas, haciéndolo adecuado para su uso en diversos entornos de laboratorio e industriales. El colorante se emplea a menudo en histología y microscopía para teñir proteínas y otros materiales biológicos, ya que proporciona un buen contraste y visibilidad. En aplicaciones alimentarias, se utiliza para mejorar el atractivo visual de los productos, aunque su uso está regulado en muchos países debido a posibles preocupaciones de salud. Ponceau S también es conocido por su estabilidad en condiciones ácidas, pero puede degradarse en condiciones alcalinas o con exposición prolongada a la luz. En general, es un compuesto versátil con una utilidad significativa tanto en campos científicos como comerciales.
