Description

Menadione Sodium Bisulfite Hydrate is a stable, water-soluble derivative of vitamin K3, widely used as a vital nutritional supplement and feed additive. This compound is essential for supporting proper blood coagulation and bone metabolism in animals. It is a critical ingredient for manufacturers in the animal nutrition, pharmaceutical, and feed premix industries seeking a reliable and bioavailable source of vitamin K activity.

Application

• Animal Feed & Nutrition: Primary use as a vitamin K supplement in poultry, swine, and aquaculture feeds to prevent hemorrhagic disorders and support bone health.
• Veterinary Pharmaceuticals: Formulated into injectable or oral solutions for the treatment and prevention of vitamin K deficiency in livestock and companion animals.
• Feed Premixes & Concentrates: Incorporated into vitamin-mineral premixes due to its stability and compatibility with other feed ingredients.
• Aquaculture: Added to fish and shrimp feed to enhance survival rates and prevent bleeding issues.
• Pharmaceutical Intermediates: Serves as a key starting material or intermediate in the synthesis of other vitamin K analogs and pharmaceutical compounds.
• Research & Development: Used in biochemical research and as a standard in analytical laboratories for quality control of feed and food products.

Quality Control

Our Menadione Sodium Bisulfite Hydrate is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for feed and nutritional applications. A comprehensive Certificate of Analysis (COA) detailing assay, purity, and specific tests is provided with every shipment to guarantee consistent quality and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
