CAS 54827-17-7: 3,3′,5,5′-Tetrametilbencidina
Descripción:
3,3′,5,5′-Tetrametilbencidina (TMB) es un compuesto orgánico comúnmente utilizado como sustrato cromogénico en ensayos de inmunoabsorción ligados a enzimas (ELISA) y otras aplicaciones bioquímicas. Se caracteriza por su capacidad para sufrir oxidación, lo que resulta en un cambio de color que puede medirse cuantitativamente, lo que lo hace valioso en diagnósticos de laboratorio. TMB es un derivado de la benzidina, que presenta cuatro grupos metilo unidos a los anillos de benceno, lo que mejora su solubilidad y estabilidad. El compuesto es típicamente un sólido amarillo pálido a incoloro a temperatura ambiente y es soluble en disolventes orgánicos y agua bajo ciertas condiciones. TMB es sensible a la luz y al aire, lo que puede llevar a su degradación; por lo tanto, a menudo se almacena en recipientes oscuros y herméticos. Aunque TMB se utiliza ampliamente en entornos de investigación y clínicos, es importante manejarlo con cuidado debido a su potencial toxicidad y propiedades carcinogénicas asociadas con su estructura de benzidina. Se deben seguir los protocolos de seguridad adecuados al trabajar con este compuesto para minimizar los riesgos de exposición.
