Nero Reattivo 5

Descrizione:

Nero Reattivo 5 è un colorante sintetico comunemente utilizzato nell'industria tessile per tingere cotone e altre fibre di cellulosa. Appartiene alla classe dei coloranti reattivi, che formano legami covalenti con la fibra, garantendo una buona resistenza al lavaggio e alla luce. Questo colorante azoico è caratterizzato dal suo colore nero scuro e dall'alta solubilità in acqua, rendendolo adatto a vari processi di tintura. La struttura chimica di Nero Reattivo 5 include più anelli aromatici e gruppi funzionali che facilitano la sua reattività con i gruppi idrossilici nella cellulosa. È importante notare che, sebbene Nero Reattivo 5 sia efficace per tingere, ha sollevato preoccupazioni ambientali e sanitarie a causa della sua potenziale tossicità e della formazione di sottoprodotti nocivi durante la degradazione. Misure regolatorie sono in atto in alcune regioni per limitarne l'uso e garantire un maneggiamento sicuro. In generale, Nero Reattivo 5 è un colorante ampiamente utilizzato con applicazioni industriali significative, ma richiede una gestione attenta per mitigare il suo impatto ambientale.

C.I.Reactive Black 5

CAS: 17095-24-8

C.I.Reactive Black 5 is a reactive dye that can be used to detect bacterial growth in the presence of sodium carbonate, which is added to the reaction solution at a concentration of 0.1M. The dye has been shown to inhibit enzyme activities, such as nitrogen atoms and anhydrous sodium, and disrupt bacterial growth by binding to cell surfaces. This dye is also able to photobind with bacterial cells in nutrient solutions and kinetic experiments, leading to inhibition of cell division through the disruption of DNA replication.
