Vitamin K3 Menadione Nicotinamide Bisulfite (MNB)

Menadione nicotinamide bisulfite (CAS 73581-79-0) is a water-soluble complex of menadione and nicotinamide, formulated to deliver stable vitamin K3 activity in aqueous systems.

Where is Vitamin K3 Menadione Nicotinamide Bisulfite (MNB) used?

• Animal nutrition: primary source of supplemental vitamin K3 in poultry and swine
• Aquaculture feed premixes: water solubility critical for uniform dosing
• Pharmaceuticals: injectable and oral liquid formulations requiring a stabilized, water-compatible vitamin K source
• Food and nutrition: vitamin K3 fortification agent where dry menadione would present processing challenges
• Multi-vitamin concentrate blends: antioxidant properties support stability
• Feed and nutraceutical production: preservative properties
• Its bisulfite complexation resolves the handling and solubility limitations of menadione.

Good to know: This chemical structure makes it highly practical for liquid and feed premix manufacturing where the parent compound alone would be unsuitable.

Commercial specifications

• Feed-grade material standardized to 50% menadione activity
