2',3'-Dideoxyadenosine (ddA) is a purine 2',3'-dideoxynucleoside with adenine attached to a sugar lacking both the 2'- and 3'-hydroxyl groups. CH64015 is identified by CAS 4097-22-7, molecular formula C10H13N5O2, molecular weight 235.24, and PubChem CID 20039.
After conversion to the corresponding triphosphate, the missing 3'-hydroxyl prevents further DNA-chain extension after polymerase incorporation. That property is the basis for its chain-termination context in DNA-polymerase and dideoxy-sequencing research.

常见问题
Why is 2',3'-dideoxyadenosine a chain terminator?
It lacks a 3'-hydroxyl, so once the corresponding ddNTP is incorporated by DNA polymerase, no further nucleotide can be added and the chain terminates — the principle behind dideoxy sequencing.
How is ddA different from 2'-deoxyadenosine?
2'-Deoxyadenosine lacks only the 2'-hydroxyl and can extend a chain; 2',3'-dideoxyadenosine lacks both 2'- and 3'-hydroxyls and acts as a chain terminator. 2'-deoxyadenosine is cataloged separately.
