Pharmadite amidites are manufactured in scales of up to multi-hundred kilos, under certified ISO 9001 quality systems at SAFC Supply Solutions manufacturing facility in Hamburg, Germany.

We start with traceable, non-animal and very pure raw materials, use highly controlled synthesis and purification processes, validated analytical methods and cleaning processes, all governed with strict change control and documentation to yield unprecedented high quality products with purity ratings at 99.5% or higher for DNA and 99.0% or higher for RNA.

All remaining impurities, if present, are identified and characterized at a level of 0.1%.

The high level of control and documentation imposed at every step of the production process support regulatory requirements to make Pharmadite amidites ideal for pharmaceutical applications.

Manufacturing
Pharmadite amidites are prepared from DMT-protected nucleosides and the phosphitylating agent "bis-amidite." To ensure the highest quality our production process begins with starting materials that possess stringent specifications and defined impurity profiles. The crude phosphoramidites are then purified by preparative HPLC, dried and packaged. Our HPLC production line is cleaned using validated cleaning methods and cleaning verification is performed prior to each batch. Reactions are conducted at a minimum synthesis scale of 50 kg per batch. Each processing step is monitored using analytical in-process controls, including HPLC.

Production Process

Specifications
Pharmadite amidites are characterized by their exceptional purity and well-defined impurity profile. In particular, they are essentially free from contaminants which interfere in coupling reactions, such as other nucleosidic or non-nucleosidic phosphoramidites (P(III)-contaminants).

Quality system and production process designed to meet pharmaceutical standards.
Control of starting materials and production process is a key factor in the synthesis procedure of RNA Pharmadite. The phosphitylating reagent is controlled at a level of 0.1% P(III)- impurities. RNA Pharmadite amidites are purified by preparative HPLC in a highly automated purification plant.

Having been ISO 9001 certified since 1993, Proligo Reagents' production facility in Hamburg, Germany (GE) guarantees a reproducible quality, a predictable and controlled production:
  • Robust process parameters
  • In-process controls with specifications
  • Batch integrity
  • Change control
  • Batch record review
  • Process database and trend analysis
  • Validated cleaning procedures
