Used primarily in the formulation of sunscreens and skincare products due to its strong UV-absorbing properties, especially in the UVB range. It helps protect the skin from sun damage by absorbing harmful radiation. Also employed in the synthesis of liquid crystals for display technologies, where it acts as a building block for mesogenic compounds. Additionally, it serves as an intermediate in organic synthesis, particularly in the preparation of fragrances, pharmaceuticals, and other cinnamic acid derivatives. Its natural occurrence in some plants makes it useful in studies related to photoprotection in biological systems.
