General description

Menadione is a prothrombogenic compound and belongs to the Vitamin K class of compounds, which are necessary for the biosynthesis of prothrombin and other blood clotting factors. It is used as a model quinone in cell culture and in vivo investigations. It is obtained as a catabolic product of phylloquinone and circulating precursor of tissue menaquinone-4 in rats.
Menadione (K3) is a fat-soluble vitamin precursor and catabolic product of oral phylloquinone (vitamin k1) in the intestine.


Menadione (K3) may be used as an analytical reference standard for the quantification of the analyte in biological fluids using liquid chromatography technique.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
