2'-O-NMA-G (iBu) CE Phosphoramidite is a 2'-modified RNA building block: 5'-O-(4,4'-dimethoxytrityl)-N2-isobutyrylguanosine with a 2'-O-[2-(methylamino)-2-oxoethyl] group and a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. It is identified by CAS 1025783-22-5, molecular formula C47H59N8O10P, molecular weight 927.0, PubChem CID 168441196, and InChIKey BNLNDNDXCOPBTF-NCJSJSGWSA-N.
"NMA" denotes the 2'-O-N-methylacetamide group (2'-O-CH2-C(=O)-NH-CH3), a permanent 2'-O-modification rather than a protecting group. The cited 2'-modification literature is used here as background for the 2'-position modification class, not as a standalone performance claim for this catalog item. The monomer couples through a standard 3'-phosphoramidite (3'→5' linkages), the 5'-DMT is removed each cycle, and the N2-isobutyryl base-protecting group is removed during final deprotection.

Anwendungskontext
- 2'-O-N-methylacetamide (NMA) modification: a permanent 2'-O-amide substituent at the 2'-position.
- 2'-modification literature context: the cited literature supports the broader 2'-position modification class; avoid rewriting it as a standalone performance claim for this catalog item.
- 3'→5' coupling monomer: the 3'-phosphoramidite couples to form 3'→5' linkages; the 5'-DMT is removed each cycle and the N2-isobutyryl base-protecting group is removed during final deprotection.

Häufig gestellte Fragen
What does 'NMA' stand for in this monomer?
NMA is the 2'-O-N-methylacetamide group — a 2'-O-CH₂-C(=O)-NH-CH₃ substituent (2'-O-[2-(methylamino)-2-oxoethyl]). It is a permanent 2'-O-modification, not a protecting group.
