Used primarily as a surfactant and stabilizer in industrial applications, particularly in the production of resins and polymers. It acts as an antioxidant and UV stabilizer in plastics, helping to extend the lifespan of polymer-based materials exposed to outdoor conditions. Commonly found in coatings, adhesives, and sealants to improve water resistance and durability. Also serves as an intermediate in the synthesis of specialty chemicals for lubricants and fuel additives. Its long hydrophobic chain makes it effective in modifying surface properties and enhancing compatibility in non-polar systems.
