5'-O-DMT-N6-benzoyl-2'-deoxyadenosine is 2'-deoxyadenosine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group and an N6-benzoyl base-protecting group. CH64099 is identified by CAS 64325-78-6, molecular formula C38H35N5O6, molecular weight 657.72, PubChem CID 2724489, and InChIKey LPICNYATEWGYHI-WIHCDAFUSA-N.
It is a doubly protected precursor for DNA phosphoramidite/oligonucleotide synthesis: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle, while the N6-benzoyl group masks the adenine exocyclic amine and is removed at final deprotection.

Frequently Asked Questions
What do the two protecting groups on this deoxyadenosine do?
The 5'-O-DMT (dimethoxytrityl) group is an acid-labile protection on the 5'-hydroxyl that is removed at the start of each oligonucleotide chain-elongation cycle; the N6-benzoyl group protects the adenine exocyclic amine during synthesis and is removed at final deprotection.
How does it differ from N6-benzoyl-2'-deoxyadenosine?
Both carry an N6-benzoyl-protected adenine, but this one also has a 5'-O-DMT group on the 5'-hydroxyl. N6-benzoyl-2'-deoxyadenosine (without DMT) is cataloged separately.
What identifiers should match for CH64099?
Match CAS 64325-78-6, molecular formula C38H35N5O6, molecular weight 657.72, PubChem CID 2724489, and InChIKey LPICNYATEWGYHI-WIHCDAFUSA-N.
