Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of antithyroid medications. Acts as a photosensitizer in photopolymerization processes and finds use in some UV-curable systems. Investigated for its potential in nucleic acid research due to its ability to incorporate into RNA in place of uracil, thereby modifying RNA stability, function, and translation processes. Also explored in the design of metal sensors and coordination compounds for analytical applications.
