5'-O-DMT-2'-deoxyuridine is 2'-deoxyuridine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group. CH64104 is identified by CAS 23669-79-6, molecular formula C30H30N2O7, molecular weight 530.57, PubChem CID 90230, and InChIKey BYGKUWPLEGHFKX-ZRRKCSAHSA-N.
It is a 5'-protected precursor for DNA phosphoramidite/oligonucleotide synthesis: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle. Because uracil has no exocyclic amine, no base protecting group is required.

Contexto de aplicación
- 5'-DMT 5'-OH protection: the acid-labile 4,4'-dimethoxytrityl group protects the 5'-hydroxyl and is removed at the start of each oligonucleotide chain-elongation cycle.
- No base protection needed: uracil has no exocyclic amine, so this building block requires no base protecting group.
- Phosphoramidite precursor context: a 5'-protected 2'-deoxyuridine precursor toward DNA phosphoramidite building blocks.

Preguntas frecuentes
Why does 5'-O-DMT-2'-deoxyuridine have no base protecting group?
Uracil has no reactive exocyclic amine, so unlike A, C, and G it needs no base protection. Only the 5'-hydroxyl is protected with the acid-labile DMT group, which is removed at the start of each oligonucleotide chain-elongation cycle.
How does it differ from 2'-deoxyuridine?
It carries a 5'-O-(4,4'-dimethoxytrityl) group on the 5'-hydroxyl, whereas 2'-deoxyuridine is unprotected. 2'-deoxyuridine is cataloged separately.
