LNA-G(iBu) CE Phosphoramidite is the locked nucleic acid (LNA) guanosine building block for oligonucleotide synthesis: a 2'-O,4'-C-methylene-bridged (locked) N2-isobutyrylguanosine with a 5'-O-(4,4'-dimethoxytrityl) group and a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65047 is identified by CAS 206055-77-8, molecular formula C45H54N7O9P, molecular weight 867.9, PubChem CID 136760121, and InChIKey UUBFSNDSLDOIDQ-NIQOLRRHSA-N.
The cited LNA literature discusses locked 2'-O,4'-C-methylene sugar structures in relation to oligonucleotide binding affinity and nuclease resistance. As a phosphoramidite, the 3'-phosphoramidite couples to the growing chain, the acid-labile 5'-DMT is removed each cycle, and the N2-isobutyryl base group is removed at final deprotection.

Questions fréquentes
What residue identity does this LNA amidite provide?
It provides the locked (LNA) guanosine residue identity through its 3'-phosphoramidite coupling group, with 5'-DMT removed each cycle and N2-isobutyryl removed at final deprotection.
How does it differ from the LNA-A(Bz) amidite?
Both are LNA (locked) phosphoramidites, but this one has an N2-isobutyryl-protected guanine, whereas the LNA-A(Bz) amidite has an N6-benzoyl adenine. Each LNA base is cataloged separately.
