(S)-GNA-G(iBu) CE Phosphoramidite is the glycol nucleic acid (GNA) guanine building block for oligonucleotide synthesis: an (S)-propylene-glycol nucleoside bearing an N2-isobutyryl guanine, a DMT-protected hydroxyl, and a (2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65057 is identified by CAS 182625-68-9, molecular formula C42H52N7O7P, molecular weight 797.9, PubChem CID 136859130, and InChIKey GOUPKQZMFOWLOW-AUNMUFMCSA-N.
GNA is described in the cited literature as a simplified nucleic acid with an acyclic propylene glycol phosphodiester backbone, and the cited (S)-GNA literature discusses heteroduplex formation with RNA. As a phosphoramidite, the reactive phosphoramidite couples to the growing chain, the acid-labile DMT is removed each cycle, and the N2-isobutyryl base group is removed at final deprotection.

Application context
- GNA coupling monomer: the (2-cyanoethyl N,N-diisopropyl)phosphoramidite is the reactive group that couples to the growing GNA chain in solid-phase synthesis.
- Acyclic glycol backbone: GNA replaces the sugar-phosphate backbone with an acyclic propylene glycol phosphodiester backbone; the cited (S)-GNA literature discusses heteroduplex formation with RNA.
- DMT + N2-isobutyryl protection: the acid-labile DMT is removed each cycle, and the N2-isobutyryl base group is removed at final deprotection.

Frequently Asked Questions
How does it differ from the (S)-GNA-A(Bz) amidite?
Both are (S)-GNA phosphoramidites, but this one has an N2-isobutyryl-protected guanine, whereas the (S)-GNA-A(Bz) amidite has an N6-benzoyl adenine. Each GNA base is cataloged separately.
