Reactive Black 5

Description:
Reactive Black 5 is a synthetic dye commonly used in the textile industry for dyeing cotton and other cellulose fibers. It belongs to the class of reactive dyes, which form covalent bonds with the fiber, ensuring good wash and light fastness. This azo dye is characterized by its dark black color and high solubility in water, making it suitable for various dyeing processes. The chemical structure of Reactive Black 5 includes multiple aromatic rings and functional groups that facilitate its reactivity with hydroxyl groups in cellulose. It is important to note that while Reactive Black 5 is effective for dyeing, it has raised environmental and health concerns due to its potential toxicity and the formation of harmful byproducts during degradation. Regulatory measures are in place in some regions to limit its use and ensure safe handling. Overall, Reactive Black 5 is a widely utilized dye with significant industrial applications, but it necessitates careful management to mitigate its environmental impact.

  • C.I.Reactive Black 5

    CAS:
    <p>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.</p>
