  • A/-halamine compounds may have a range of different stabilities in environments that comprise organic content, for example biological fluids and other protein-based contaminants. This stability range may be based on the dissociation constant of each A/-halamine compound which permits the chloronium ion to transfer to other amines within the organic content. The loss of the chloronium ion can cause the A/-halamine compound to lose some or all of its biocidal activity. For example, organic content within an environment with may quench the functionality of the /V-halamine. This instability presents a challenge to using N-halamine compounds in various applications where it is desirable to kill microbes within an environment with organic content. The organic content can also decrease the biocidal activity of QACs through other mechanisms.
