CAS 845-10-3: Sal sódica de rojo de metilo
Descripción:
Sal sódica de rojo de metilo, con el número CAS 845-10-3, es un indicador de pH comúnmente utilizado en titulaciones y diversas aplicaciones de laboratorio. Es la forma de sal sódica del rojo de metilo, que es un ácido débil que exhibe un cambio de color de rojo a amarillo a medida que el pH pasa de ácido a neutro. Específicamente, el rojo de metilo tiene un rango de transición de pH de aproximadamente 4.4 a 6.2, lo que lo hace particularmente útil para detectar cambios de pH en entornos ácidos. El compuesto es típicamente soluble en agua, y su solución aparece roja en condiciones ácidas y amarilla en condiciones neutras a alcalinas. Sal sódica de rojo de metilo se emplea a menudo en medios microbiológicos y como un tinte biológico debido a su capacidad para indicar cambios de pH. Además, es importante manejar esta sustancia con cuidado, ya que puede ser un irritante leve. En general, Sal sódica de rojo de metilo es una herramienta valiosa tanto en química analítica como en investigación biológica para monitorear los niveles de pH.
