  • Applications

    Deoxyinosine (CAS 890-38-0) is primarily used as a DNA oligonucleotide building block for degenerate primers and probes, supporting broad-target PCR, sequencing, and diagnostic workflows. It is employed in aptamer design and in modified oligos to broaden base-pairing flexibility. It also serves as a component in custom nucleic acid reagents for gene research and genetic analysis, and as a standard nucleoside building block in nucleotide chemistry and sequencing tool development in biotech labs.
