2'-O-Methyluridine (2'-OMe-U, Um) is uridine with a 2'-O-methyl group on the ribose. CH64023 is identified by CAS 2140-76-3, molecular formula C10H14N2O6, molecular weight 258.23, and PubChem CID 102212. It has the same molecular formula as 5-methyluridine but a different methyl position and structure.
The same 2'-O-methyl motif appears in natural RNA modifications and in synthetic oligonucleotide research. In the cited literature, 2'-O-methyl ribonucleosides are discussed for nuclease resistance and RNA affinity, while Um is treated as a natural RNA-modification reference.

常见问题
How is 2'-O-methyluridine different from 5-methyluridine?
Both share the formula C10H14N2O6, but 2'-O-methyluridine (Um) carries the methyl on the 2'-oxygen of the ribose, while 5-methyluridine (ribothymidine) carries it on carbon 5 of the base. They are constitutional isomers and are listed separately.
