Synthesis and application of new 2-methyl-1,3- dioctadecyl-1H-benzo[d]imidazol-3-ium cationic surfactant

Cationic surfactants are a part of the surface active compounds. They have a positively charged part (head) of a molecule while the rest of the molecule (tail) usually consists of one or more saturated or unsaturated hydrocarbon chains. Their primary role is to lower the surface tension of water. Cationic surfactants are often active ingredients in commercial products for washing, disinfection and preservation in products for professional, industrial and everyday use. Since cationic surfactants often have antimicrobial properties, new compounds could be used for novel formulations of anti SARS-CoV-2 disinfectants. In this paper we presented a synthesis of 2- methyl1, 3-dioctadecyl-1H-benzo[d]imidazol-3-ium cationic surfactant. The compound was characterized by NMR, IR, LC-MS, and elemental analysis. The compound was used for the fabrication of a surfactant sensor and was tested on antimicrobial properties for selected microorganisms.
