Base-protected Nucleosides
2'-O-4'-C-Locked-rA(Bz)
Quick view. We supply 2'-O-4'-C-Locked-rA(Bz) as a protected locked-nucleic-acid nucleoside intermediate for high-affinity oligonucleotide monomer synthesis. CAS 209968-94-5. Catalog target purity: Specification on request.

Product profile
2'-O-4'-C-Locked-rA(Bz) is classified as nucleoside or protected nucleoside intermediate (Formula C18H17N5O5).
2'-O-4'-C-Locked-rA(Bz) can serve as a starting material, protected intermediate or analytical comparator in nucleoside and nucleotide route development.
For 2'-O-4'-C-Locked-rA(Bz), high-affinity monomers require careful positional design; over-substitution may increase off-target binding or complicate synthesis.
