Widely used in molecular biology and pharmaceutical research as a key intermediate in nucleoside analog synthesis. Plays a critical role in the development of antiviral and anticancer drugs due to its structural similarity to natural nucleosides. Commonly employed in the design of reverse transcriptase inhibitors, especially in therapies targeting HIV and hepatitis viruses. Also utilized in enzymatic assays and as a building block in oligonucleotide synthesis for diagnostic probes and gene editing technologies. Its stereochemistry allows for high specificity in binding to biological targets, enhancing drug efficacy and reducing off-target effects.
