Used as a photostabilizer in polymers and coatings, this compound helps prevent degradation caused by UV light exposure. It is particularly effective in protecting plastics, paints, and adhesives from yellowing and embrittlement due to sunlight. Its ability to absorb UV radiation and dissipate it as heat makes it valuable in outdoor applications where long-term durability is required. It is also employed in specialty inks and optical materials where clarity and resistance to aging are important.
