Used in the synthesis of fluorescent probes and bioimaging agents due to its ability to integrate into DNA structures and emit detectable signals upon binding. Commonly applied in molecular biology for tracking DNA replication and repair mechanisms. Also utilized in the development of nucleoside analogs for antiviral and anticancer research. Its amino group allows for easy conjugation with labels such as fluorophores or biotin, enhancing its utility in diagnostic assays and high-throughput screening. Shows promise in expanding the genetic alphabet for synthetic biology applications.
