CAS :<p>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.</p>Formule :C25H19ClN10O16S5•Na5Degré de pureté :Min. 95%Masse moléculaire :1,026.21 g/molDisperse red 277
