CAS 23647-14-5: SPADNS
Descripción:
SPADNS, o ácido 3-amino-5-mercapto-1,2,4-triazol-1-sulfónico, es un compuesto químico comúnmente utilizado como reactivo en química analítica, particularmente en ensayos colorimétricos para la determinación de ciertos iones metálicos, como el plomo y el cadmio. Se caracteriza por su capacidad para formar complejos coloreados estables con estos metales, que pueden ser medidos cuantitativamente. SPADNS es típicamente un sólido cristalino que es soluble en agua, lo que lo hace adecuado para diversas aplicaciones acuosas. El compuesto presenta un anillo de triazol, que contribuye a su reactividad y propiedades de complejación. Además, SPADNS es conocido por su sensibilidad y especificidad en la detección de iones metálicos, lo que lo hace valioso en el monitoreo ambiental y en procesos de control de calidad. Se deben tomar precauciones de seguridad al manipular SPADNS, ya que puede representar riesgos para la salud si se ingiere o inhala. En general, SPADNS es una herramienta importante en química analítica para el análisis de metales traza.
