2',3',5'-Tri-O-benzoyl-2-thiouridine

2',3',5'-Tri-O-benzoyl-2-thiouridine is a chemically modified nucleoside where the 2-oxo group of uridine is replaced by sulfur and the hydroxyl groups are benzoylated. This protected thionucleoside serves as a key synthetic intermediate in oligonucleotide chemistry for constructing RNA analogs, facilitating research into nucleic acid structure, function, and stability in biochemical studies.
