Widely used in UV protection applications due to its strong absorption of ultraviolet light. Commonly added to plastics, coatings, adhesives, and textiles to prevent degradation caused by sunlight exposure. Found in sunscreens, cosmetics, and sunglasses to protect both the product formulation and the skin from UV damage. Also used in perfumes as a fragrance fixative to prolong scent longevity. Serves as a photoinitiator in printing inks and dental materials, where it helps initiate curing when exposed to UV light. In research, serves as a photosensitizer in photochemical reactions and studies involving energy transfer.
