This functional phosphoramidite is used to introduce click handles univerally (5′ internal and 3′end) into oligonucleotides under standard conditions for solid phase synthesis. Afterwards the oligonucleotide (RNA, PNA, DNA) can be efficiently conjugated using a copper-catalyzed click reaction to azide-functionalized moieties such as fluorescent dye azides and azido amino acids
