Descrizione:

Acido 2-naftalensolfonico, 6-[2-[2-ammino-4-[(2-idrossietil)ammino]fenil]diazenil]-3-[2-[4-[[4-[2-[7-[2-[2-ammino-4-[(2-idrossietil)ammino]fenil]diazenil]-1-idrossi-3-sulfo-2-naftalenil]diazenil]fenil]ammino]-3-solfofenil]diazenil]-4-idrossi-, sale di sodio (1:3), comunemente noto con il suo numero CAS 6428-38-2, è un composto organico complesso caratterizzato dalla sua struttura di colorante azoico. Questa sostanza presenta più gruppi funzionali, inclusi gruppi acido solforico e amminici, che contribuiscono alla sua solubilità in acqua e alle sue potenziali applicazioni nella tintura e come indicatore di pH. La presenza di anelli di naftalene e fenile nella sua struttura suggerisce che potrebbe mostrare forti proprietà coloranti, rendendola utile in varie applicazioni industriali, in particolare nei tessuti e nelle inchiostri. Inoltre, la forma di sale sodico del composto migliora la sua stabilità e solubilità in soluzioni acquose. La sua struttura intricata potrebbe anche indicare una potenziale attività biologica, giustificando ulteriori indagini sui suoi impatti ambientali e sulla salute.
