7-TFA-ap-7-Deaza-2',3'-dideoxyadenosine is a 2',3'-dideoxy 7-deazaadenosine that carries a 3-(trifluoroacetamido)prop-1-ynyl amino-linker at the C7 position. CH64050 is identified by CAS 114748-71-9, molecular formula C16H16F3N5O3, molecular weight 383.32, PubChem CID 14630112, and InChIKey WUXCPWCITSUNMX-WDEREUQCSA-N.
The trifluoroacetyl (TFA) group protects a primary amine on the aminopropynyl linker, while the 2',3'-dideoxy sugar defines the chain-terminating nucleoside identity. The cited literature discusses amine-linker nucleosides and 7-deazapurine C7 functionalization in fluorescent labeling and DNA-sequencing research.

Frequently Asked Questions
What do 'TFA' and 'ap' mean in the name?
'ap' is the aminopropynyl (3-aminoprop-1-ynyl) linker at C7, and 'TFA' is the trifluoroacetyl group protecting that linker's primary amine.
Why is it a chain terminator?
It is a 2',3'-dideoxynucleoside, which is the sugar pattern associated with chain-terminator designs in DNA-sequencing research. CH64050 also carries a protected C7 amino-linker.
