This compound, adenosine 5'-monophosphate disodium salt hydrate (5'-AMP disodium salt hydrate), is a naturally occurring ribonucleotide crucial for energy metabolism, signal transduction, and nucleic acid biosynthesis. It functions as a key intermediate in purine nucleotide pathways and serves as a substrate or product in enzymatic reactions involving kinases (e.g., adenylate kinase, AMPK), nucleotidases, and polymerases. Widely used in biochemical and molecular biology research for assays of nucleotide metabolism, DNA/RNA synthesis, enzyme kinetics, and as an analytical standard (e.g., HPLC, NMR). In pharmaceutical development, it acts as a reference for nucleoside-based antiviral and anticancer agents. The disodium salt hydrate form provides high water solubility and stability for lab and therapeutic applications.
