Used primarily as an intermediate in the synthesis of hindered amine light stabilizers (HALS), this compound plays a key role in enhancing the weatherability and longevity of polymers exposed to UV radiation. It is incorporated into plastics, coatings, and adhesives to prevent degradation caused by sunlight, heat, and oxygen. Its derivatives help maintain color, strength, and appearance in automotive parts, agricultural films, and exterior building materials. Due to its stability and reactivity, it is also utilized in specialty organic syntheses requiring controlled radical inhibition.
