- Rubber Industry: It is extensively used as a secondary vulcanization accelerator and a primary antioxidant for natural and synthetic rubbers (e.g., SBR, NBR, CR). It improves the heat resistance and longevity of rubber products like tires, belts, and hoses.
- Polymer Additive: Serves as a heat stabilizer and antioxidant for various polymers, including polyethylene (PE) and polypropylene (PP), preventing thermal degradation during processing and end-use.
- Corrosion Inhibitor: It is an effective corrosion inhibitor for copper and its alloys, forming a protective film on the metal surface, which is useful in cooling systems and metalworking fluids.
- Pharmaceutical Intermediate: Used as a building block in the synthesis of certain active pharmaceutical ingredients (APIs), including some antiulcer drugs.
- PVC Stabilization: Functions as a heat stabilizer in the formulation of polyvinyl chloride (PVC) products to enhance their durability.
