Tridecylbenzene is primarily used as a chemical intermediate in the production of surfactants and detergents. Its alkylbenzene structure makes it suitable for creating linear alkylbenzene sulfonates (LAS), which are key components in many household and industrial cleaning products. Additionally, it finds application in the formulation of lubricants and plasticizers, where it enhances performance and stability. In the industrial sector, it is utilized as a solvent and in the synthesis of specialty chemicals. Its properties also make it a useful ingredient in the production of emulsifiers and dispersants for various formulations.
