MMT-C6-Amine-Linker Phosphoramidite is a non-nucleoside modifier for adding a reactive amino group to an oligonucleotide: a six-carbon (hexyl) linker carrying a monomethoxytrityl (MMT)-protected primary amine at one end and a (2-cyanoethyl N,N-diisopropyl)phosphoramidite at the other. Its PubChem-backed identity includes CAS 114616-27-2, molecular formula C35H48N3O3P, molecular weight 589.7, and PubChem CID 9873234.
Coupling attaches an aminohexyl arm to the oligonucleotide (typically the 5'-terminus). The acid-labile MMT group protects the amine during synthesis and is removed afterward to reveal a free primary amine on a C6 spacer. The cited amino-modifier literature describes aliphatic amino groups reacting with electrophiles, allowing dyes, biotin, or other chemical species to be attached to oligonucleotides.

应用背景
- Amino conjugation handle: provides a primary amine on a six-carbon spacer at the oligonucleotide terminus.
- Electrophile-reactive amine: the cited literature describes aliphatic amino groups reacting with electrophiles to attach dyes, biotin, or other species.
- MMT-protected during synthesis: the acid-labile MMT group masks the amine during assembly and is removed to expose it afterward.

常见问题
What does this amino-linker do?
It provides a primary amine on a six-carbon spacer at an oligonucleotide terminus. After the MMT protecting group is removed, the amine can react with electrophiles to attach dyes, biotin, or other conjugates.
Why is the amine MMT-protected?
The monomethoxytrityl (MMT) group masks the reactive amine during solid-phase synthesis. It is acid-labile and removed afterward to reveal the free primary amine for conjugation.
