Used as a photosensitizer in photopolymerization processes, enabling rapid curing of inks, coatings, and adhesives upon exposure to light.

Plays a role in organic synthesis as an oxidizing agent, particularly in the conversion of diols to diketones.

Employed in electrochemical studies due to its reversible redox behavior, making it suitable for sensor development and charge-transfer research.

Also investigated for its potential in photodynamic therapy owing to its ability to generate reactive oxygen species under light irradiation.
