This chemical is primarily utilized in the field of nucleic acid research and drug development. It serves as a modified nucleoside, specifically designed for the synthesis of oligonucleotides with unique properties. The azidomethyl group allows for click chemistry applications, enabling the attachment of various functional groups or labels, which is useful in tracking and studying nucleic acid interactions. The 7-TFA (trifluoroacetyl) and 7-deaza modifications enhance stability and resistance to enzymatic degradation, making it valuable in the development of therapeutic oligonucleotides, such as antisense drugs or siRNA. Its application is particularly relevant in creating probes for diagnostic assays or in the design of novel therapeutic agents targeting genetic disorders or viral infections.
