Used primarily as an antioxidant in the rubber industry, it helps prevent the degradation of rubber products caused by heat, oxygen, and ozone exposure. This extends the lifespan and maintains the performance of tires, belts, hoses, and other rubber goods. It is also employed in the stabilization of lubricants and greases, enhancing their durability under high-temperature conditions. Additionally, it finds application in the production of dyes and as an intermediate in organic synthesis, contributing to the development of various chemical compounds.
