5'-O-DMT-5-methyl-2'-O-methyluridine is 2'-O-methyl-5-methyluridine (its base is 5-methyluracil) carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group. CH64119 is identified by CAS 153631-19-7, molecular formula C32H34N2O8, molecular weight 574.6, PubChem CID 10438068, and InChIKey VFLOXJCZWDDILQ-NODMTMHWSA-N.
It is a 2'-OMe-modified RNA phosphoramidite precursor context: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle. In the cited literature, 2'-O-methyl ribonucleosides/residues are discussed for nuclease resistance and RNA affinity. Because the 5-methyluracil base has no exocyclic amine, no base protecting group is required.

Contexte d’application
- 5'-DMT 5'-OH protection: the acid-labile 4,4'-dimethoxytrityl group protects the 5'-hydroxyl and is removed at the start of each RNA chain-elongation cycle.
- 2'-OMe modification context: cited literature discusses 2'-O-methyl residues in relation to nuclease resistance and RNA affinity.
- No base protection needed: the 5-methyluracil base has no exocyclic amine, so this building block requires no base protecting group.

Questions fréquentes
How does it differ from 5'-O-DMT-2'-O-methyluridine?
This one has a 5-methyluracil base (an extra methyl on the base), whereas 5'-O-DMT-2'-O-methyluridine has a plain uracil base. That one is cataloged separately.
