CAS 76-61-9: Azul de timol
Descripción:
Azul de timol es un indicador de pH comúnmente utilizado en diversas aplicaciones químicas, particularmente en titulaciones y como un tinte biológico. Es un colorante sulfonftaleína que exhibe un cambio de color dependiendo del pH de la solución, pasando de amarillo en niveles de pH ácidos a azul en condiciones alcalinas. El compuesto es soluble en agua y alcohol, lo que lo hace versátil para diferentes configuraciones experimentales. Azul de timol tiene dos rangos de transición de pH distintos, lo que le permite indicar un espectro más amplio de acidez y alcalinidad. Además de su función como indicador de pH, Azul de timol también se utiliza en microbiología y bioquímica para fines de tinción debido a su capacidad para unirse a componentes celulares. Su estructura química incluye un grupo fenólico, lo que contribuye a sus propiedades ácidas. Se deben tener en cuenta consideraciones de seguridad, ya que Azul de timol puede causar irritación al contacto con la piel o los ojos, y se deben seguir procedimientos de manejo adecuados en entornos de laboratorio.
