Used primarily as a UV-absorbing agent in cosmetic formulations, especially in sunscreens and skin care products. Its ester structure enhances lipid solubility, allowing better interaction with skin lipids and improved topical stability. Acts as a protective barrier against ultraviolet radiation by absorbing UVB rays. Also employed in some pharmaceutical preparations as a prodrug intermediate due to its biocompatible ester linkage. Shows mild antioxidant properties, contributing to the preservation of light-sensitive ingredients in formulations.
