3′-O-N3-dATP trisodium

3′-O-N3-dATP trisodium (3′-O-Azidomethyl dATP trisodium) is the sodium salt form of 3′-O-N3-dATP. This compound is a modified nucleotide used for DNA polymerases. Acting as a reversible terminator, 3′-O-N3-dATP trisodium enhances Raman scattering (SERS) at 2125 cm-1, allowing for continuous DNA sequence analysis.
