Spacer-C6 Phosphoramidite is a non-nucleotide (abasic) spacer building block: a six-carbon (hexyl) spacer carrying a 5'-O-(4,4'-dimethoxytrityl) group and a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. Its PubChem-backed identity includes CAS 158041-82-8, molecular formula C36H49N2O5P, molecular weight 620.8, and PubChem CID 117768145.
Coupling inserts a non-nucleotide six-carbon spacer into the oligonucleotide backbone in place of a nucleotide — non-nucleotide chains can be incorporated into oligonucleotides this way (for example, to join segments or introduce a defined gap). The spacer couples through its 3'-phosphoramidite, and its 5'-DMT is removed each cycle so chain assembly continues.

Application context
- Non-nucleotide spacer insertion: introduces a six-carbon abasic spacer into the oligonucleotide backbone in place of a nucleotide.
- Chain-compatible: couples through a 3'-phosphoramidite and carries a 5'-DMT that is removed each cycle, so synthesis can continue past the spacer.
- Backbone linker: non-nucleotide chains can be incorporated into oligonucleotides to join segments or introduce a defined gap.

Frequently Asked Questions
What is a spacer phosphoramidite?
It is a non-nucleotide (abasic) building block that inserts a spacer unit into the oligonucleotide backbone in place of a nucleotide. It couples through a 3'-phosphoramidite and carries a 5'-DMT (removed each cycle) so chain assembly continues normally.
What does the 'C6' mean?
C6 denotes the length of the spacer — a six-carbon (hexyl) chain. Shorter (C2, C3) and longer (C12) variants and ethylene-glycol spacers give correspondingly different spacings.
What identifiers should match for CH65097?
Use CAS 158041-82-8, molecular formula C36H49N2O5P, molecular weight 620.8, PubChem CID 117768145, and InChIKey AEDFSPMNECTXJM-UHFFFAOYSA-N.
