5'-O-DMT-2'-deoxyinosine is 2'-deoxyinosine (hypoxanthine base) carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group. CH64106 is identified by CAS 93778-57-5, molecular formula C31H30N4O6, molecular weight 554.60, PubChem CID 136192437, and InChIKey IYNGMVFRUKBGNM-OYUWMTPXSA-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 the hypoxanthine base has no exocyclic amine, no base protecting group is required.

应用背景
- 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: the hypoxanthine base has no exocyclic amine, so this building block requires no base protecting group.
- Phosphoramidite precursor context: a 5'-protected 2'-deoxyinosine precursor toward DNA phosphoramidite building blocks.

常见问题
Why does 5'-O-DMT-2'-deoxyinosine have no base protecting group?
The hypoxanthine base of 2'-deoxyinosine has no reactive exocyclic amine, so 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.
What base does 2'-deoxyinosine contain?
It contains hypoxanthine, the deaminated form of the adenine base. This record is the 5'-O-DMT-protected precursor.
