This compound is widely used as a UV absorber and stabilizer in acrylic polymers, coatings, and adhesives due to its benzotriazole moiety. It is particularly valuable in optical materials, such as lenses and films, where long-term UV resistance is critical. Researchers also employ it in photoactive polymer synthesis and as a monomer for functionalized surfaces.
