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 a solvent in resins, varnishes, and pesticides due to its ability to dissolve both polar and non-polar substances. Found in paint removers and cleaning agents for industrial equipment. Also utilized in the manufacture of pharmaceuticals, perfumes, and rubber chemicals. Its reactivity makes it valuable in organic synthesis for creating cyclohexanone oxime and other derivatives.
