Description

Menadionesodiumdisulfite CAS NO 6147-37-1 is a water-soluble derivative of vitamin K3, specifically a sodium bisulfite adduct of menadione. This compound is valued for its stability and bioavailability, serving as a critical source of vitamin K activity in various formulations. It is primarily required by manufacturers in the animal feed, pharmaceutical, and nutritional supplement industries to ensure proper blood coagulation and bone metabolism.

Application

• Animal Feed Additive: A key vitamin K source in poultry, swine, and aquaculture feed premixes to prevent hemorrhagic conditions and support bone health.
• Pharmaceutical Intermediates: Used in the synthesis of more complex vitamin K analogs and active pharmaceutical ingredients (APIs).
• Nutritional Supplements: Incorporated into vitamin premixes and multivitamin formulations for human and veterinary use.
• Aquaculture and Pet Food: Essential vitamin fortification in fish feed and premium pet nutrition products.
• Research & Development: Serves as a standard or reagent in biochemical research and analytical method development.
• Cosmetic Applications: Potential use in specialized skincare formulations for its reported properties.
