Used primarily as a photosensitive compound in the production of photoresists for microelectronics and printed circuit boards. It acts as a crosslinking agent when exposed to UV light, enabling the creation of precise patterns on surfaces. Also employed in the synthesis of dyes and pigments due to its ability to form stable complexes. In research, it serves as a reagent for studying photochemical reactions and polymerization processes. Its application extends to the development of advanced materials with light-responsive properties.
