Used primarily in the production of nylon-6 and nylon-6,6, serving as a key intermediate in the synthesis of adipic acid and caprolactam. Widely employed as an industrial solvent for resins, lacquers, and pesticides due to its ability to dissolve both polar and non-polar substances. Also utilized in the formulation of pesticides, pharmaceuticals, and rubber chemicals. Plays a role in the manufacture of peroxides, such as cyclohexanone peroxide, which act as initiators in polymerization reactions. Common in paint and coating removers for its effective solvency and moderate evaporation rate.
