Widely used as a quaternary ammonium compound, this chemical serves as a powerful disinfectant and biocide in various settings. It is commonly formulated into sanitizers and cleaners for use in healthcare facilities, food processing plants, and households due to its effectiveness against a broad spectrum of microorganisms, including bacteria, viruses, and fungi.

Its surfactant properties enhance its ability to penetrate microbial cell walls, leading to rapid disinfection. It is particularly valued in hard water conditions where other disinfectants may lose efficacy, as it remains stable and active.

In industrial water systems, it controls microbial growth in cooling towers, paper mills, and metalworking fluids. It is also used in textile and leather processing to provide antimicrobial finishes and preservation.

Due to its cationic nature, it adheres well to surfaces, providing residual antimicrobial activity after application. However, care is required in use, as it can be inactivated by anionic surfactants and certain organic materials.
