This chemical is primarily used in the field of molecular biology and biochemistry, particularly in the synthesis of modified oligonucleotides. It serves as a crucial building block for creating DNA or RNA sequences with specific modifications, enabling advanced research in genetic studies, diagnostics, and therapeutic development. Its application is significant in the development of antisense oligonucleotides, which are used to regulate gene expression or target specific RNA molecules. Additionally, it plays a role in the study of nucleic acid interactions and the design of probes for detecting genetic mutations or variations. Its modified structure allows for enhanced stability and specificity in various biochemical assays and experimental protocols.
