  • Applications

    2-Ethylresorcinol (CAS 31154-44-6) is used as a chemical intermediate in the synthesis of dyes and pigments and as a building block for specialty aromatic compounds; it can also serve as a precursor for UV-stabilizers and antioxidants for plastics, coatings, adhesives, and other polymers; in industrial manufacturing it can function in phenolic resins and related monomer systems; it may be employed as an intermediate in fragrance and cosmetic chemistry, and as a precursor in pharmaceutical synthesis or other fine chemicals, subject to formulation limits and local regulations.
