Dicyclohexylamine (DCHA) is widely used as a corrosion inhibitor in various industrial applications, including metalworking fluids, boiler water treatment, and lubricants. It forms a protective layer on metal surfaces, preventing oxidation, rust, and extending the lifespan of equipment.

In the production of polyurethanes and resins, DCHA acts as a catalyst or neutralizer for isocyanates, improving physical properties such as durability and flexibility.

In the pharmaceutical industry, DCHA serves as an intermediate in the synthesis of various drugs, including antihistamines and anti-inflammatory agents. Its chemical structure makes it a valuable building block in organic synthesis.

Additionally, DCHA is employed in the production of rubber chemicals, where it acts as an accelerator in vulcanization processes, enhancing the durability and elasticity of rubber products.

In agricultural applications, it is used as a component in the formulation of pesticides and herbicides, helping to improve crop protection and yield.

Lastly, DCHA finds use in the manufacture of dyes and pigments, where it contributes to the stability and colorfastness of the final products. It is also utilized in separation processes and solvent extraction in chemical industries.
