Used in molecular biology and biochemistry research as a building block for DNA synthesis. Commonly employed in enzymatic reactions involving DNA polymerases and kinases. Serves as a substrate or inhibitor in studies of nucleotide metabolism and signal transduction pathways. Also utilized in the preparation of labeled nucleotides for use in DNA sequencing, PCR, and other genetic analysis techniques. Its disodium salt form enhances solubility and stability in aqueous solutions, making it suitable for in vitro applications.
