N3-Cyanoethyl-dT CE-phosphoramidite
Modified Phosphoramidites , class Other modifications
| Catalog # | CBT-P-110 |
| Compound | N3-Cyanoethyl-dT CE-phosphoramidite |
| Chemical Name | N3-(2-Cyanoethyl)-1-[2-deoxy-5-O-(4,4'-dimethoxytriphenylmethyl)-ß-D-erythro-pentofuranosyl]-thymidine 3'-[(2-cyanoethyl)-(N,N-diisopropyl)]-phosphoramidite |
| Formula | C43H52N5O8P |
| Molecular Weight | 797.88 g/mol |
| Properties | Storage at -18°C The cyanoethyl group is commonly used as P(III) protecting group and is cleaved during oligonucleotide synthesis by beta-elimination under alkaline conditions affording acrylonitrile. Acrylonitrile acts as alkylating agent and partially adds to N3 of dT. As a result, a full length oligonucleotide is obtained in which thymine is partially replaced by an N3-cyanoethylthymine residue. We offer the phosphoramidite building block CBT-P-110 as a standard to elucidate side product formation during oligonucleotide synthesis. |
