5-TFA-aa-2'-deoxyuridine is 2'-deoxyuridine carrying an aminoallyl amino-linker at the C5 position of uracil, with the linker's terminal amine protected as a trifluoroacetamide (TFA). CH64058 is identified by CAS 115794-55-3, molecular formula C14H16F3N3O6, molecular weight 379.29, PubChem CID 10959831, and InChIKey MBPYSSRDTGXWJD-HFVMFMDWSA-N.
The aminoallyl arm provides a protected amine-linker motif on a 2'-deoxy nucleoside. The cited labeling literature discusses amine-linker nucleosides in covalent fluorophore attachment and indirect labeling research for nucleic acids.

Frequently Asked Questions
What does 'aa' (aminoallyl) mean here?
'aa' is the aminoallyl linker, a 3-aminoprop-1-enyl arm at C5. Its terminal amine is protected as a trifluoroacetamide (TFA).
How is it different from 5-TFA-aa-Uridine?
This is the 2'-deoxy (DNA) version; 5-TFA-aa-Uridine is the ribonucleoside (RNA) version. They are cataloged separately.
