Used primarily as a plasticizer in polymers to enhance flexibility and workability, especially in polyvinyl chloride (PVC) and other resin systems. It improves the durability and low-temperature performance of plastics. Also functions as a lubricant additive and stabilizer in industrial oils, providing resistance to oxidation and thermal degradation. Employed in coatings and adhesives to modify viscosity and improve film formation. Its long alkyl chain contributes to water repellency, making it suitable for use in waterproofing agents and corrosion inhibitors. Additionally, it serves as an intermediate in the synthesis of surfactants and emulsifiers for industrial applications.
