Used as an intermediate in organic synthesis, particularly in the production of dyes and pharmaceuticals. It serves as a building block in the development of photoinitiators for UV-curable coatings and inks due to its ability to absorb ultraviolet light and generate free radicals. Also employed in research settings for studying photochemical reactions and energy transfer processes. Its aromatic structure makes it useful in the design of fluorescent probes and optoelectronic materials.
