General Information

Phytonadione Impurities and Phytonadione

Daicel Pharma is capable of offering Phytonadione impurity standards such as Phytonadione Impurity B, Phytonadione Impurity A, Phytonadione Diol Impurity, Phytonadione Diol Impurity-1 and more. The effectiveness, stability, and safety of Phytonadione is affected by impurities. Daicel Pharma can synthesize custom Phytonadione impurities according to global standards and regulations and worldwide delivery.

Phytonadione [CAS: 84-80-0] belongs to the class of phylloquinone. It functions as a cofactor, as a plant metabolite, and as a human metabolite. It is vitamin K and a phylloquinone member.

Phytonadione: Use and Commercial Availability

Oral phylloquinone treats prothrombin deficiency. It also treats hypoprothrombinemia. Parenteral phylloquinone (administered through intravenous, intramuscular, or subcutaneous routes) treats coagulation disorders caused by deficiencies in the production of coagulation factors II, VII, IX, and X due to vitamin K deficiency or any interference with vitamin K activity. This medicine is available under brand names such as Aquamephyton, Konakion, Mephyton, Vitamin K1, and Vitaped.

Phytonadione Structure and Mechanism of ActionPhytonadione Structure and Mechanism of Action

The chemical name of Phytonadione is 2-Methyl-3-[(2E,7R,11R)-3,7,11,15-tetramethyl-2-hexadecen-1-yl]-1,4-naphthalenedione. Its chemical formula is C31H46O2, and its molecular weight is approximately 450.7 g/mol.

Phytonadione is necessary for the formation of prothrombinogen and other blood clotting factors in the liver.

Phytonadione Impurities and Synthesis

Phytonadione impurities refer to unintended substances or contaminants present in Phytonadione1, a synthetic form of vitamin K. These impurities can impact the product’s effectiveness, stability, and safety.

Daicel Pharma provides a Certificate of Analysis (CoA) for various Phytonadione impurity standards, including Phytonadione Impurity B, Phytonadione Impurity A, Phytonadione Diol Impurity, Phytonadione Diol Impurity-1, and more. Our analytical facility, certified under cGMP, issues a comprehensive CoA and detailed characterization information such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. Additional characterization details, like 13C-DEPT, can be provided upon request. Daicel Pharma is qualified to provide Phytonadione impurities and labeled compounds for assessing the effectiveness of generic Phytonadione. We offer highly pure Cis-Phytonadione-D7, Phytonadione-D7 (Mixture of Cis & Trans), and Tran-Phytonadione-D7, deuterium-labeled Phytonadione standard, essential for bioanalytical research and Bioavailability/Bioequivalence (BA/BE) studies.
