Description

Riboflavin-5'-Phosphate Sodium Salt Dihydrate is the biologically active, water-soluble form of vitamin B2, essential for numerous metabolic redox reactions. This high-purity form offers superior bioavailability and stability compared to standard riboflavin, making it a critical ingredient for advanced nutritional and pharmaceutical formulations. It is primarily required by manufacturers in the nutraceutical, pharmaceutical, and food & beverage fortification industries seeking reliable, high-quality sources for their products.

Application

• Pharmaceutical Formulations: Used in injectable solutions, multivitamin preparations, and therapeutic products where immediate bioavailability is crucial.
• Dietary Supplements & Nutraceuticals: A key active ingredient in high-performance vitamin B-complex capsules, tablets, and liquid supplements.
• Food & Beverage Fortification: Employed to enrich infant formula, clinical nutrition products, cereals, and energy drinks, complying with FCC standards.
• Cosmetic & Personal Care: Incorporated into skincare products for its purported antioxidant properties and skin-conditioning benefits.
• Animal Feed & Veterinary Products: Serves as a vital nutrient premix in feed for livestock, poultry, and pets to support growth and health.
• Biochemical Research & Cell Culture: Used as a defined component in microbiological media and cell culture applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in original packaging until use to prevent degradation and clumping.
