Used in biochemical research as a ribonucleotide substrate for studying RNA synthesis mechanisms, particularly in in vitro transcription reactions catalyzed by RNA polymerases. Serves as a substrate in enzymatic assays involving RNA polymerases, kinases, and other nucleotide-dependent enzymes. Essential for the production of RNA transcripts and investigation of RNA metabolism. Valuable in the development of antiviral agents targeting RNA viruses due to its role in nucleic acid synthesis. Also employed in molecular biology techniques such as RNA labeling and synthesis of modified RNAs when specific ribonucleotides are required.
