DMTr-2'-O-EOE-rA(Bz)-3'-CE-Phosphoramidite is used in oligonucleotide synthesis and contains a 2'-O-ethoxyethyl (EOE) group at the 2'-position of adenosine (rA), along with benzoyl (Bz) protection on the adenine amino group. Additionally, it features a cyanoethyl (CE) group at the 3'-end to facilitate efficient coupling reactions during solid-phase synthesis. It is employed to introduce modified adenosine residues into RNA sequences, enhancing stability and target specificity.
