This chemical is primarily used in the synthesis of modified oligonucleotides, particularly in the field of nucleic acid research and therapeutic development. It serves as a key building block in the construction of oligonucleotide sequences with specific modifications, enabling enhanced stability, binding affinity, and resistance to nuclease degradation. Applications include the development of antisense oligonucleotides, siRNA, and other gene-silencing technologies. Its incorporation into oligonucleotide strands allows researchers to study gene function, develop targeted therapies for genetic disorders, and explore potential treatments for diseases such as cancer and viral infections. Additionally, it is utilized in diagnostic assays and molecular biology tools to improve the accuracy and efficiency of nucleic acid detection and analysis.
