Used primarily as an intermediate in the synthesis of high-performance light stabilizers, especially hindered amine light stabilizers (HALS). These stabilizers are critical in protecting polymers, coatings, and plastics from degradation caused by ultraviolet (UV) light and oxidative stress. The compound contributes to enhancing the longevity and durability of materials exposed to outdoor weathering, such as polyolefins, polyurethanes, and automotive coatings. Its derivatives help prevent color fading, cracking, and loss of mechanical strength in sunlight-exposed products. It is also utilized in specialty applications requiring high thermal and photostability.
