Used in biochemical research for RNA synthesis studies and as a substrate in enzyme assays involving kinases and polymerases. Supports cell culture applications where nucleotide precursors are required for nucleic acid production. Employed in molecular biology techniques such as in vitro transcription to produce RNA from DNA templates. Also utilized in studies of cellular energy transfer and nucleotide metabolism due to its role as an activated phosphate donor. Stable form suitable for laboratory storage and handling in enzymatic reactions.
