Saccharin 1-methylimidazole (SMI) Chemical Properties,Usage,Production

Description

Saccharin 1-methylimidazole is a chemical activator that has been commonly used in solid-phase synthesis of DNA and RNA oligonucleotides. It catalyzes the phosphoramidite coupling reaction of the 5'' hydroxy of immobilized nucleosides and the amine group of nucleoside phosphoramidite. Saccharin 1-methylimidazole has been used to synthesize single-stranded DNA (ssDNA) oligonucleotides that are resistant to nuclease digestion.

Uses

Saccharin 1-Methylimidazole is a reagent used for nucleic acid synthesis (1,2).
