Used primarily as an intermediate in the synthesis of antioxidants and UV stabilizers for polymers, this compound contributes to enhancing the thermal and light stability of plastics, rubber, and adhesives. Its aldehyde and phenolic functional groups allow further chemical modifications, making it valuable in producing specialty chemicals, including fragrances and pharmaceuticals. It is also employed in the development of resins and coatings where long-term durability under environmental stress is required.
