1. Metal Corrosion Inhibition and Rust Prevention
This is its most core application. As a highly effective copper corrosion inhibitor, it provides rust protection for various metals such as silver, copper, lead, nickel, and zinc, and is widely used in rust-preventive oils, greases, vapor phase corrosion inhibitors, and metalworking fluids.

2. Polymer Materials
It is used as a stabilizer and UV absorber in polymer materials to protect plastics and other materials from photoaging.

3. Plant Growth Regulation
It can be used as a plant growth regulator.

4. Lubricating Oil
As a lubricating oil additive, it acts as an antioxidant, anti-wear agent, and metal deactivator.

5. Water Treatment and Antifreeze
It is an important component of corrosion and scale inhibitors in industrial circulating water treatment and is also used in automotive antifreeze to protect cooling system metals.

6. Other Chemical Applications
It is used as a stabilizer or catalyst in organic synthesis and also has applications in polymer production and other fields.
