N-Octylcyclohexane is primarily used as a solvent in various industrial applications due to its non-polar nature and stability. It is often employed in the formulation of lubricants and greases, where it helps to reduce friction and wear on mechanical parts. Additionally, it serves as a diluent in the production of polymers and resins, aiding in the control of viscosity and improving processing efficiency. In the field of coatings and paints, it is utilized to enhance the flow and leveling properties, ensuring a smooth and even finish. Its chemical stability also makes it suitable for use in high-temperature applications, such as heat transfer fluids. Furthermore, n-Octylcyclohexane is sometimes used in research and development as a reference compound in chromatographic analysis and other laboratory procedures.
