The chemical substance known as "5'-O-(4,4-Dimethoxytrityl)-2'-O-[(tert-butyl)dimethylsilyl]-N-isobutyrylguanosine-3'-(2-cyanoethyl-N,N-diisopropyl)phosphoramidite" is a phosphoramidite derivative of guanosine, commonly used in the field of nucleic acid synthesis, particularly for the solid-phase synthesis of oligonucleotides. This compound features several key functional groups, including a dimethoxytrityl protecting group at the 5' position, which aids in the selective coupling of nucleotides during synthesis. The presence of a tert-butyl dimethylsilyl group at the 2' position provides additional protection against unwanted reactions, enhancing the stability of the nucleoside during the synthesis process. The isobutyryl group contributes to the overall stability and reactivity of the molecule, while the cyanoethyl phosphoramidite moiety is crucial for the formation of phosphodiester bonds in oligonucleotide synthesis. Overall, this compound is characterized by its complex structure, which facilitates the efficient and controlled assembly of nucleic acid sequences in laboratory settings.
