Propylcyclohexane is primarily used as a solvent in various industrial applications due to its non-polar nature and stability. It is commonly employed in the formulation of paints, coatings, and adhesives, where it helps dissolve other substances and improve application properties. In the manufacturing sector, it serves as a reaction medium in organic synthesis, particularly in processes requiring a non-reactive solvent. Additionally, it finds use in the production of rubber and plastics, where it acts as a processing aid to enhance material properties. Its low reactivity and volatility also make it suitable for use in certain cleaning agents and degreasers.
