2'-Deoxyguanosine (dmf) CE Phosphoramidite is the fully protected 2'-deoxyguanosine building block for DNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-N2-dimethylformamidine-2'-deoxyguanosine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65006 is identified by CAS 330628-04-1, molecular formula C43H53N8O7P, molecular weight 824.9, PubChem CID 136334904, and InChIKey YRQAXTCBMPFGAN-UNHDIWNRSA-N.
Nucleoside phosphoramidites are the coupling monomers used in automated solid-phase oligonucleotide synthesis: the 3'-phosphoramidite is the reactive group that couples to the growing chain, the acid-labile 5'-DMT is removed at the start of each cycle, and the N2-dmf base group is removed at final deprotection.

Contexte d’application
- DNA 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.
- 5'-DMT 5'-OH protection: the acid-labile 4,4'-dimethoxytrityl group is removed at the start of each chain-elongation cycle.
- N2-dmf base protection: the dimethylformamidine group masks the guanine exocyclic amine during synthesis and is removed at final deprotection.

Questions fréquentes
What makes this a phosphoramidite building block?
It carries a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group — the reactive coupling group used in automated solid-phase DNA synthesis. It also has an acid-labile 5'-O-DMT group (removed each cycle) and an N2-dimethylformamidine (dmf) base protection (removed at final deprotection).
How does it differ from 2'-deoxyguanosine (iBu) phosphoramidite?
Both are 5'-O-DMT 2'-deoxyguanosine phosphoramidites, but this one uses an N2-dimethylformamidine (dmf) base protection rather than isobutyryl. The isobutyryl amidite is cataloged separately.
