Product profile
3'-O-MOE-5MeU-2'-phosphoramidite is classified as other phosphoramidites (Formula C43H55N4O10P; molecular weight 818.90 g/mol).
3'-O-MOE-5MeU-2'-phosphoramidite is relevant to high-stability antisense oligonucleotide gapmer and affinity-tuning research.
For 3'-O-MOE-5MeU-2'-phosphoramidite, mOE placement needs design control, especially when RNase H recruitment or steric profile matters.
