UNA-U CE Phosphoramidite is the unlocked nucleic acid (UNA) uracil building block for oligonucleotide synthesis: an acyclic (C2'-C3' bond-opened) ribonucleoside bearing a uracil base, a 5'-O-(4,4'-dimethoxytrityl) group, and a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65062 is identified by CAS 1120329-48-7, molecular formula C46H53N4O10P, molecular weight 852.9, PubChem CID 100942372, and InChIKey MHRGEJFLFYZLJI-LZOZAVILSA-N.

The cited UNA literature discusses unlocked acyclic nucleic acid structures in relation to duplex characteristics. As a phosphoramidite, the 3'-phosphoramidite couples to the growing chain and the acid-labile 5'-DMT is removed each cycle. Because uracil has no exocyclic amine, no base protecting group is required.

Contexto de aplicación

  • UNA coupling monomer: the 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite is the reactive group that couples to the growing oligonucleotide chain in automated solid-phase synthesis.
  • Unlocked acyclic modification: the cited UNA literature discusses C2'-C3' bond-opened ribose structures in relation to oligonucleotide duplex characteristics.
  • No base protection needed: uracil has no exocyclic amine, so this monomer requires no base protecting group (only the acid-labile 5'-DMT, removed each cycle).

Preguntas frecuentes

Why does the UNA-U amidite have no base protecting group?

Uracil has no reactive exocyclic amine, so it needs no base protection. The monomer carries only the acid-labile 5'-O-DMT group (removed each cycle) and the reactive phosphoramidite coupling group.
