Phosphoramidite used to incorporate a deoxyadenosine into an oligonucleotide, with a methylated backbone.

Monomer for H-phosphonate nucleic acid synthesis.

Phosphoramidite used to incorporate a 8-amino-modified deoxyadenosine into an oligonucleotide.

Isosteric with adenine but offers a different pi-electron distribution and thus an altered dipole moment.

Allows for incorporation of a halogenated nucleoside into oligonucleotides for crystallographic studies and crosslinking studies of protein-DNA and RNA-DNA complexes.
