Used as a key intermediate in the synthesis of benzophenone-based UV absorbers, particularly in the production of high-performance sunscreen agents and stabilizers for polymers. Its structure enables effective absorption of ultraviolet light, making it valuable in cosmetic formulations to protect against UV degradation. Also utilized in the development of light-stable coatings and plastics, where it helps prevent yellowing and material breakdown under prolonged sunlight exposure. Its reactivity allows for further chemical modifications to enhance solubility and compatibility in various matrices.
