2',3'-Dideoxythymidine (ddT) is a pyrimidine 2',3'-dideoxynucleoside with thymine attached to a sugar lacking both the 2'- and 3'-hydroxyl groups. CH64018 is identified by CAS 3416-05-5, molecular formula C10H14N2O4, molecular weight 226.23, and PubChem CID 65119. It is distinct from the didehydro analog d4T.
After conversion to the corresponding triphosphate, the missing 3'-hydroxyl prevents further DNA-chain extension after polymerase incorporation. That property defines its chain-termination context in DNA-polymerase and dideoxy-sequencing research.

よくある質問
Why is 2',3'-dideoxythymidine a chain terminator?
It lacks a 3'-hydroxyl, so once its triphosphate is incorporated by DNA polymerase no further nucleotide can be added and the chain terminates — the principle behind dideoxy sequencing.
Is ddT the same as the didehydro d4T analog?
No. CH64018 is 2',3'-dideoxythymidine; d4T is 2',3'-didehydro-2',3'-dideoxythymidine, a different compound with an added double bond.
