CAS 596-01-0: α-Naftolftaleína
Descripción:
α-Naftolftaleína, con el número CAS 596-01-0, es un compuesto orgánico que pertenece a la clase de los ftaleínas, conocidas por su uso como indicadores de pH. Se caracteriza por su estructura, que consiste en dos anillos de naftaleno conectados por un grupo de ácido ftálico. Este compuesto típicamente aparece como un sólido cristalino e insoluble en agua, pero soluble en disolventes orgánicos como el alcohol y el éter. α-Naftolftaleína exhibe un cambio de color en respuesta a las variaciones de pH, pasando de incoloro en condiciones ácidas a un tono rosa o rojo en ambientes alcalinos, lo que lo hace útil en valoraciones y otras aplicaciones analíticas. Además, tiene aplicaciones en tintura y como intermediario químico en la síntesis orgánica. Sin embargo, es importante manejar este compuesto con cuidado, ya que puede representar riesgos para la salud al ser expuesto. En general, α-Naftolftaleína es una sustancia valiosa tanto en entornos de laboratorio como industriales debido a sus propiedades distintivas y reactividad.

CAS:1-Naphtholphthalein is a diazonium salt that is used as an optical sensor. It reacts with hydroxyl groups in the presence of hydrochloric acid and potassium dichromate to produce a light-sensitive red dye. The reaction products are then exposed to light to produce a color change. This process can be repeated many times, allowing for the detection of low concentrations of analytes. 1-Naphtholphthalein is also used as a template molecule in acyl halide synthesis reactions.Pureza:Min. 95%Ref: 3D-FN00195
