Used in biochemical research as a substrate or intermediate in nucleotide metabolism studies. Supports enzyme assays involving kinases and phosphorylases due to its phosphate group structure. Employed in cell culture media formulations to promote cell growth under stress conditions. Also utilized in molecular biology for nucleotide analog synthesis and metabolic pathway analysis. Additionally, serves as a standard in HPLC or mass spectrometry analyses for identifying and quantifying related compounds in biological samples.
