Trifluorothymidine
Trifluorothymidine (CAS: 70-00-8), with the molecular formula C10H11F3N2O5, is a fluorinated nucleoside analog. It functions as a substrate for thymidine kinases and, upon phosphorylation, can be incorporated into DNA, leading to DNA damage. This property makes it valuable for studying DNA repair mechanisms and the mechanisms of thymidylate synthase inhibition. It is supplied by Tech Serve Solutions with an assay of ≥99% by HPLC.
