- Rubber Industry: Acts as a primary and secondary antioxidant in the vulcanization of natural rubber (NR), styrene-butadiene rubber (SBR), and nitrile rubber (NBR). It effectively prevents aging caused by heat and oxygen.
- Corrosion Inhibition: Widely used as a corrosion inhibitor to protect copper, bronze, and other copper alloys from tarnishing and degradation, especially in industrial water systems and antifreeze solutions.
- PVC Stabilization: Functions as a heat stabilizer in the production of polyvinyl chloride (PVC) products to enhance their durability.
- Pharmaceuticals & Agrochemicals: Serves as a key intermediate in the synthesis of various pharmaceutical drugs (such as omeprazole) and specialized agrochemicals.
- Plating Additive: Used as a brightening agent in copper plating baths to improve the quality and appearance of the final plated surface.
