5'-O-DMT-N2-isobutyryl-2'-deoxyguanosine is 2'-deoxyguanosine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group and an N2-isobutyryl base-protecting group. CH64101 is identified by CAS 68892-41-1, molecular formula C35H37N5O7, molecular weight 639.70, PubChem CID 135445746, and InChIKey RMQXDNUKLIDXOS-ZGIBFIJWSA-N.
It is a doubly protected precursor for DNA phosphoramidite/oligonucleotide synthesis: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle, while the N2-isobutyryl group masks the guanine exocyclic amine and is removed at final deprotection.

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.
- N2-isobutyryl base protection: the isobutyryl group masks the guanine exocyclic amine during synthesis and is removed at final deprotection.
- Phosphoramidite precursor context: a doubly protected 2'-deoxyguanosine precursor toward DNA phosphoramidite building blocks.

常见问题
What do the two protecting groups on this deoxyguanosine do?
The 5'-O-DMT (dimethoxytrityl) group is an acid-labile protection on the 5'-hydroxyl that is removed at the start of each oligonucleotide chain-elongation cycle; the N2-isobutyryl group protects the guanine exocyclic amine during synthesis and is removed at final deprotection.
How does it differ from N2-isobutyryl-2'-deoxyguanosine?
Both carry an N2-isobutyryl-protected guanine, but this one also has a 5'-O-DMT group on the 5'-hydroxyl. N2-isobutyryl-2'-deoxyguanosine (without DMT) is cataloged separately.
