2’-Deoxyadenosine is widely used in molecular biology and biochemistry research, particularly in the synthesis of DNA. It serves as a crucial building block in the creation of oligonucleotides, which are essential for techniques like PCR, DNA sequencing, and gene synthesis. Additionally, it plays a role in studying DNA repair mechanisms and understanding cellular processes involving nucleotide metabolism. In medicine, it is investigated for its potential in antiviral and anticancer therapies, as it can interfere with DNA replication in rapidly dividing cells. Its derivatives are also explored in the development of nucleoside analogs for treating viral infections and certain cancers.
