Used primarily as an intermediate in the synthesis of light stabilizers, especially in the production of hindered amine light stabilizers (HALS). These stabilizers are critical in protecting polymers, coatings, and plastics from degradation caused by UV radiation. The compound contributes to enhancing the durability and lifespan of materials exposed to sunlight, such as automotive parts, outdoor textiles, and construction materials. Its derivatives help prevent discoloration, cracking, and loss of mechanical strength in polymers. Also finds use in specialty chemical formulations requiring high thermal and photo-oxidative stability.
