Riboflavin-5′-Phosphate Sodium Salt Dihydrate CAS 6184-17-4 (FMN-Na) | High Water-Soluble Active Coenzyme Vitamin B2 Raw Material for Export

1. Basic Product Specifications
Many overseas pharmaceutical, health food and feed manufacturers are troubled by the drawbacks of ordinary riboflavin: poor water solubility limits injection production, low bioavailability, and solubilizers are required for liquid formulas, which raise production costs.
Riboflavin-5′-Phosphate Sodium Salt Dihydrate (FMN-Na) is the activated coenzyme form of vitamin B2. It requires no secondary conversion in the human body and dissolves quickly in cold water, making it a premium alternative to conventional riboflavin for global buyers.

2. Core Purchasing Advantages for Overseas Manufacturers
2.1 High Bioactivity Suitable for Intravenous Formulations
FMN-Na inherently carries coenzyme activity, directly participating in human metabolism and delivering faster efficacy. It is widely used in intravenous nutrition fluids and injections for vitamin B2 deficiency, fully complying with formulation standards of pharmaceutical factories in Europe, America and Southeast Asia.
2.2 Excellent Water Solubility Simplifies Production Formulas
It dissolves completely in room-temperature cold water without additional solubilizers, greatly cutting formula costs for oral liquids, liquid feed premixes and water-soluble meal replacement powders, and simplifying full production line procedures.
2.3 One-Stop Sourcing of Four Grades
We maintain in-stock supply of Pharmaceutical Injection Grade, Food Fortification Grade, Aquatic & Livestock Feed Grade, BS Biochemical Reagent Grade. One supplier covers multiple production lines, eliminating tedious communication, quality inspection and price comparison with multiple vendors.
2.4 Multi-Functional Raw Material Expands Client Product Lines
Beyond pharmaceutical and nutritional applications, it is applicable to biological specimen staining, fluorescent probe synthesis, agricultural photosensitizer additives and biodegradable polymer modifiers, helping overseas manufacturers expand diversified business segments.
2.5 Ocean-Shipping Packing Reduces Cargo Loss
Packed with light-proof & moisture-proof aluminum foil bags inside fiber drums for export. It resists oxidation and activity loss during long-distance sea transport, ensuring stable indicators upon arrival and avoiding rework or returns caused by raw material deterioration.
3. Global Main Application Fields

3.1 Pharmaceutical Manufacturing
It is used in injections and multi-vitamin tablets for angular cheilitis, glossitis, conjunctivitis, corneal neovascularization and other vitamin B2 deficiency disorders. It also serves as a key raw material for hospital intravenous nutrition infusions, with long-term bulk orders from pharmaceutical companies worldwide.
3.2 Dietary Supplements & Food Industry
Added to meal replacement powders, instant drinks, dairy products and baked goods, it delivers dual functions of nutritional fortification and natural yellow pigmentation. No extra artificial colorants are needed, meeting food additive compliance regulations across all regions.
3.3 Livestock & Aquatic Feed Industry
An essential premix raw material for global intensive farming. It compensates vitamin gaps in feed, accelerates growth of livestock and aquatic products, and improves reproduction and disease resistance, bringing large order volumes and stable repeat purchases.
3.4 Special Reagents for Biochemical Laboratories
