2'-O-C16-G (iBu) Phosphoramidite is a lipophilic 2'-modified RNA building block: 5'-O-(4,4'-dimethoxytrityl)-N2-isobutyrylguanosine with a 2'-O-hexadecyl (C16) group and a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. Its PubChem-backed identity includes CAS 2382942-32-5, molecular formula C60H86N7O9P, molecular weight 1080.3, and PubChem CID 167312664.
The 2'-O-C16 chain is a permanent 2'-O-modification — a long, fatty-acid-type lipophilic substituent rather than a protecting group. The cited 2'-modification literature discusses 2'-position sugar modifications in relation to nuclease/metabolic stability, and cited lipophilic-oligonucleotide literature discusses fatty-acid-type moieties in relation to lipid-particle and plasma-protein affinity. The monomer couples through a standard 3'-phosphoramidite (3'→5' linkages), the 5'-DMT is removed each cycle, and N2-isobutyryl protection is removed during final deprotection.

Questions fréquentes
What is the 2'-O-C16 modification?
It is a 2'-O-hexadecyl group — a long, fatty-acid-type lipophilic chain permanently attached at the 2'-position. It is not a protecting group; it stays on the finished oligonucleotide.
