1-Bromotridecane is primarily used as an intermediate in organic synthesis, particularly in the production of surfactants and detergents. Its long carbon chain makes it suitable for creating compounds that lower surface tension, which is essential in cleaning products. Additionally, it serves as a building block in the synthesis of quaternary ammonium compounds, which are widely used as disinfectants, fabric softeners, and antimicrobial agents. In research, it is employed as a reagent for introducing the tridecyl group into various molecules, aiding in the study of chemical reactions and material properties. Its application extends to the pharmaceutical industry, where it is utilized in the development of certain active ingredients and excipients.
