Used in the synthesis of photoinitiators for UV-curable coatings and inks, this compound plays a key role in polymer chemistry due to its ability to participate in radical reactions upon exposure to light. Its conjugated structure enhances reactivity in photocrosslinking systems, making it valuable in adhesives, dental materials, and electronic encapsulation where rapid curing and strong adhesion are required. It is also explored as an intermediate in pharmaceuticals and agrochemicals due to its stable aromatic and functionalized backbone.
