This TIPS-5-Ethynyl-dU-CE Phosphoramidite can be used instead of the 5-Ethynyl-dU-CE Phosphoramidite under standard conditions for solid phase synthesis. The protecting group reduces the risk of side products. The oligo is deprotected after the synthesis leading to ethynyl modified oligonucleotides.
