Used in dental materials and restorative resins as a photoinitiator to enable rapid curing under light exposure. Enhances the efficiency of polymerization in light-curable composites. Commonly found in bone cements and biomedical devices where controlled, fast setting is required. Also applied in photoresists and microfabrication processes due to its sensitivity to UV and visible light. Its fluorescent properties allow for real-time monitoring of curing depth and polymerization completeness in clinical and industrial settings.
