Used primarily as an intermediate in the production of surfactants and detergents due to its long hydrophobic alkyl chain and reactive phenolic group. It is also employed in the synthesis of antioxidants for industrial applications such as lubricants and polymers. Its structure allows for alkylation and sulfonation, making it suitable for formulating emulsifiers in agrochemicals and oilfield chemicals. Additionally, it finds use in the manufacture of resins and as a modifier in adhesives and sealants to improve water resistance and durability.
