CAS 125-20-2: Timolftaleína
Descripción:
Timolftaleína es un compuesto orgánico sintético comúnmente utilizado como indicador de pH en diversas aplicaciones químicas. Es un sólido incoloro a amarillo pálido a temperatura ambiente y exhibe un cambio de color distintivo de incoloro a azul a medida que el pH de una solución aumenta de condiciones ácidas a alcalinas, típicamente alrededor de un rango de pH de 9.3 a 10.5. Esta propiedad lo hace particularmente útil en titulaciones y otros procedimientos de química analítica. Timolftaleína es soluble en alcohol y éter, pero tiene una solubilidad limitada en agua, lo cual es una característica de muchos indicadores orgánicos. Su estructura química presenta un grupo ftalato, que es responsable de sus propiedades de cambio de color. Además de su uso en laboratorios, Timolftaleína tiene aplicaciones en el campo de la biología y la ciencia ambiental para monitorear los niveles de pH. Sin embargo, es importante manejar este compuesto con cuidado, ya que puede representar riesgos para la salud si se ingiere o inhala, y se deben observar las medidas de seguridad adecuadas durante su uso.
