Structural Study and Antibacterial Activity of Cetylpyridinium Dodecyl Sulfate Ion Pair

A bactericidal and structural study on the cetylpyridinium dodecyl sulfate ion pair has been taken. The ion pair was a subject of numerous investigations, and its properties are widely discussed in different works. However, systematic studies on the specific interionic interactions in this ion pair are absent in the literature. To fill the gap in knowledge on the structure of cetylpyridinium dodecyl sulfate, we have synthesized this ion pair and characterized it with XRD, NMR, and DFT techniques. Moreover, antibacterial activity against various bacteria strains was analyzed.
