Cyanoethyl tetraisopropylphosphorodiamidite
CAS 102691-36-1, Cat. No EN300-239576
Reagent for phosphitylation of DNA or RNA fragments
2-Cyanoethyl tetraisopropylphosphorodiamidite is a phosphitylation reagent for DNA and RNA fragment synthesis that became very important in this field of study[1]. It is a colorless liquid that is shelf-stable well well-soluble in most organic solvents[2]. The reagent is stable for hydrolysis and offers an easy procedure that requires only an activator, such as (EN300-77565), and no heating. After the reaction, which usually takes one night, chromatography can easily purify the product.
