Description

Menadione Sodium Bisulfite is a stable, water-soluble source of vitamin K activity, chemically known as the sodium bisulfite adduct of menadione. This compound is critical for ensuring proper blood coagulation and bone metabolism in animal nutrition and serves as a vital synthetic vitamin K supplement. It is primarily utilized by manufacturers in the animal feed, pharmaceutical, and nutraceutical industries to formulate premixes and dietary supplements.

Application

• Animal Feed Additive: A primary source of vitamin K3 in poultry, swine, and aquaculture feed to prevent hemorrhagic disorders and support bone health.
• Pharmaceutical Intermediates: Used in the synthesis of various vitamin K-based pharmaceutical products and injectable formulations.
• Nutraceutical & Premix Manufacturing: Incorporated into vitamin premixes and dietary supplements for consistent vitamin K activity.
• Veterinary Medicine: Formulated into treatments for vitamin K deficiency in livestock and companion animals.
• Aquaculture Feed: Essential for farmed fish and shrimp to maintain healthy growth and prevent deficiency-related mortality.
• Research & Development: Serves as a standard or reagent in biochemical and nutritional studies.
