TFA-aminoallyl-2′-deoxyuridine Phosphoramidite (CAS: 144253-90-7) is a modified nucleoside used in DNA synthesis. It incorporates an aminoallyl group on the 2′-deoxyuridine base, protected by a trifluoroacetyl (TFA) group. This enables the easy addition of reactive amino groups to synthetic oligonucleotides for labeling or conjugation with dyes or other markers.
Applications:
- Oligonucleotide Labeling: Adds amino groups for attaching dyes or labels.
- DNA Synthesis: Introduces functional groups for chemical modifications.
- Bioconjugation: Links oligonucleotides to other biomolecules.
