Used in the synthesis of antithyroid medications to regulate thyroid hormone production. Employed in research for its potential in developing nucleoside analogs used in antiviral and anticancer therapies. Acts as a photosensitizer in photopolymerization processes in some industrial applications. Investigated for use in RNA modification studies due to its structural similarity to uracil, enabling selective labeling and probing of RNA function. Also explored in the development of sensors for metal ion detection in environmental and biological samples.
