DMT-5Me-dC (Bz) -CE Phosphoramidite is a chemical structural unit that can be used in solid-phase DNA synthesis. DMT-5Me-dC (Bz) -CE Phosphoramidite can introduce the 5-methylcytidine base into the DNA chain to enhance its stability and binding affinity. DMT-5Me-dC (Bz) -CE Phosphoramidite can be used to construct modified oligonucleotides, especially for constructing locked nucleic acids (LNA) [1].
