Cyclohexylthiourea finds application primarily as a corrosion inhibitor in industrial settings, particularly in cooling water systems and metal processing. It effectively protects metal surfaces by forming a protective layer that prevents corrosive agents from causing damage. Additionally, it is used in organic synthesis as a reagent for the preparation of various chemical compounds, including pharmaceuticals and agrochemicals. Its ability to act as a stabilizing agent in certain chemical reactions also makes it valuable in research and development laboratories. In some cases, it is employed as an additive in lubricants to enhance their performance and extend the lifespan of machinery components.
