5'-O-DMT-N2-dmf-2'-deoxyguanosine is 2'-deoxyguanosine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group and an N2-dimethylformamidine (dmf) base-protecting group. CH64107 is identified by CAS 40094-22-2, molecular formula C34H36N6O6, molecular weight 624.69, PubChem CID 136407412, and InChIKey YTRIMRXIMVGPAL-ZGIBFIJWSA-N.
It is a doubly protected precursor for DNA phosphoramidite/oligonucleotide synthesis: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle, while the N2-dmf group masks the guanine exocyclic amine and is removed at final deprotection.

Häufig gestellte Fragen
What do the two protecting groups on this deoxyguanosine do?
The 5'-O-DMT (dimethoxytrityl) group is an acid-labile protection on the 5'-hydroxyl that is removed at the start of each oligonucleotide chain-elongation cycle; the N2-dimethylformamidine (dmf) group protects the guanine exocyclic amine during synthesis and is removed at final deprotection.
How does it differ from 5'-O-DMT-N2-isobutyryl-2'-deoxyguanosine?
Both are 5'-O-DMT-protected 2'-deoxyguanosines with a protected guanine N2-amine, but this one uses a dimethylformamidine (dmf) group rather than isobutyryl. The isobutyryl form is cataloged separately.
