5'-O-DMT-N2-isobutyryl-2'-O-methylguanosine is 2'-O-methylguanosine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group and an N2-isobutyryl base-protecting group. CH64118 is identified by CAS 114745-26-5, molecular formula C36H39N5O8, molecular weight 669.7, PubChem CID 135742507, and InChIKey ISQLJOGRNUQHJX-WIFIACMTSA-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, and the N2-isobutyryl group masks the guanine exocyclic amine and is removed at final deprotection. In the cited literature, 2'-O-methyl ribonucleosides/residues are discussed for nuclease resistance and RNA affinity.

用途情報
- 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.
- N2-isobutyryl base protection: the isobutyryl group masks the guanine exocyclic amine during synthesis and is removed at final deprotection.

よくある質問
How does it differ from N2-isobutyryl-2'-O-methylguanosine?
Both carry an N2-isobutyryl-protected 2'-O-methylguanosine, but this one also has a 5'-O-DMT group on the 5'-hydroxyl (as a phosphoramidite precursor). The non-DMT form is cataloged separately.
