Opis

General description

DMT-dT Pharmadite^® is a Pharmadite^® product line that represents a new class of standard protected DNA phosphoramidites designed with highly controlled impurity profiles and exceptional overall purity.Pharmadite phosphoramidites are characterized by their exceptional purity and well-defined impurity profile. In particular, they are essentially free fromcontaminants that interfere in coupling reactions, such as other nucleosidic or non-nucleosidic phosphoramidites (P(III)-contaminants). All remainingimpurities in Pharmadite phosphopramidites, if present, are identified, characterized, and quantified. The impact of any such defined impurities on the synthesis of oligonucleotides is well understood and has been shown to be insignificant.
