Used primarily as an intermediate in the synthesis of antioxidants and stabilizers for polymers and rubber. Its thiol and substituted phenolic structure makes it effective in preventing oxidative degradation in industrial materials. Commonly applied in the production of specialty chemicals for fuel and lubricant additives, where it enhances thermal stability and extends material lifespan. Also utilized in small-scale applications for agrochemicals and pharmaceuticals due to its reactivity and functional group compatibility.
