Reactive Black 39

Description:

Reactive Black 39 is a synthetic dye belonging to the class of reactive dyes, primarily used for dyeing textiles, particularly cotton and other cellulose fibers. It is characterized by its ability to form covalent bonds with the fiber, resulting in strong and durable coloration. This dye typically exhibits a dark black hue and is known for its excellent lightfastness and washfastness properties, making it suitable for various applications in the textile industry. Reactive Black 39 is soluble in water, which facilitates its application in dyeing processes. However, like many synthetic dyes, it may pose environmental concerns due to its potential toxicity and the need for proper wastewater treatment to prevent pollution. Safety data sheets indicate that it should be handled with care, as it may cause skin and eye irritation. Overall, Reactive Black 39 is valued for its vibrant color and effectiveness in textile applications, while also necessitating responsible handling and disposal practices to mitigate environmental impact.

Reactive black 39

CAS: 68259-02-9

Reactive black 39 is a benzalkonium chloride molecule that penetrates bacterial cell walls and reacts with the hydroxy groups, resulting in the formation of a reactive intermediate. This intermediate interacts with other molecules on the surface of bacteria, leading to the production of oxygen radicals. The radical initiates reactions such as oxidation and nitration, which damage the DNA and proteins in the cell. Reactive black 39 is used as a conditioning agent for wastewater treatment because it can be used to remove organic matter and heavy metals from wastewater. It also has been shown to have interactive effects with methyl glycine when treating water contaminated with phenols.
