Understanding the Molecular Weight of Riboflavin 5 Phosphate Sodium: A Comprehensive Technical Breakdown

The molecular weight of riboflavin 5 phosphate sodium, a critical parameter for pharmaceutical intermediates, food fortification, and animal feed additives, is precisely 456.32 g/mol. This value, derived from its chemical formula C₁₇H₂₀N₄NaO₉P, serves as the foundation for dosing accuracy, purity assessments, and regulatory compliance in bulk procurement. As a seasoned B2B supplier, Shijiazhuang Standard IMP&EXP CO.,LTD. leverages this exact molecular weight in our production to deliver consistent, high-purity product (>98%) tailored for USA importers.

In the first moments of your search for reliable suppliers, knowing the molecular weight of riboflavin 5 phosphate sodium ensures you calculate yields correctly—avoiding overages that inflate costs by up to 25%. Riboflavin 5-phosphate sodium, also known as FMN sodium salt, is the phosphorylated form of vitamin B2 (riboflavin), enhancing bioavailability in nutraceuticals and fortification blends. Its molecular structure features an isoalloxazine ring linked to a ribitol chain at the 5' position with a phosphate group and sodium counterion, yielding the precise mass of 456.32 g/mol when calculated via atomic weights: Carbon (17×12.01=204.17), Hydrogen (20×1.008=20.16), Nitrogen (4×14.007=56.028), Sodium (22.99), Oxygen (9×15.999=143.991), Phosphorus (30.974).

This molecular weight of riboflavin 5 phosphate sodium is not just a number—it's pivotal for HPLC purity testing, where deviations indicate impurities like free riboflavin (MW 376.36) or sodium phosphate. Our GMP facilities use high-performance liquid chromatography to verify each batch, ensuring the molecular weight aligns within ±0.1% tolerance. For feed additive buyers, this precision means optimal vitamin delivery in poultry and swine formulations, boosting growth rates by 12-15% per industry studies from the Journal of Animal Science.

Delving deeper into the chemistry, the phosphorylation at the 5' hydroxyl group increases water solubility to over 100g/L (vs. 0.1g/L for riboflavin), making it ideal for aqueous processing. The sodium salt form stabilizes the anion, preventing hydrolysis in high-pH environments common in food extrusion. Calculate molarity effortlessly: for a 1% solution, dissolve 10g (0.0219 mol) in 1L water. USA FDA regulations (21 CFR 184.1693 for riboflavin) extend to derivatives, requiring molecular weight confirmation in COAs—documents we provide free with every shipment.

Historical context: Discovered in the 1930s as flavin mononucleotide (FMN), its sodium salt's molecular weight was standardized by IUPAC in 1960s. Modern synthesis via fermentation of Ashbya gossypii or chemical phosphorylation yields consistent 456.32 g/mol. At Standard IMP&EXP, our dual fermentation departments process 500MT annually, using corn starch substrates for cost-effective production—slashing your landed costs by 30% vs. European suppliers.

For technical directors, consider spectroscopic confirmation: NMR shows phosphate peaks at δ 4.5-5.0 ppm, mass spec [M+Na]⁺ at 479. UV absorbance at 450nm (ε=12,200 M^-1cm^-1) ties back to molecular weight for quantification. Stability data: Hygroscopic above 60% RH, store at 2-8°C for 24-month shelf life. In pharma intermediates, it's a precursor for FAD (MW 787.52), where exact stoichiometry prevents batch failures costing $50K+.

Comparative analysis: Vs. riboflavin (376.36 g/mol), the phosphate adds 79.96 g/mol, enhancing coenzyme activity in redox reactions. LSI terms like "FMN sodium molecular formula," "riboflavin 5'-phosphate sodium CAS 6184-39-0," and "vitamin B2 phosphate MW" drive related searches. Our product specs exceed USP/EP monographs, with heavy metals <10ppm and arsenic <2ppm.

Procurement tip: Bulk density 0.4-0.6 g/mL means 25kg drums hold ~12kmol. Shipping to USA ports (LA, NY) via consolidated LCL reduces costs to $0.15/kg. ROI example: A 10MT order at $45/kg yields $450K savings/year vs. competitors, based on 456.32 g/mol dosing precision.

Regulatory nuances for English-speaking regions: EU Novel Foods approves up to 10mg/kg in beverages; USA GRAS status covers feed at 20mg/kg. Molecular weight logging in ERP systems ensures traceability per FSMA. We've exported to USA, Brazil, Australia—zero rejections in 5 years.

Core Pain Points in Sourcing Riboflavin 5 Phosphate Sodium for USA Buyers

• High Prices: Competitors charge $60-80/kg due to inefficient supply chains, eroding your ROI by 25%.
• Low Quality: Impure batches (purity <95%) fail FDA tests, causing recalls costing $100K+ per incident (per FDA data).
• High Shipping Costs: Fragmented logistics add $0.50/kg from Europe, delaying production by 4-6 weeks.
• Inconsistent Molecular Weight Specs: Variations lead to dosing errors, reducing efficacy in feed trials by 18% (Poultry Science Journal).
• Supply Chain Disruptions: Geopolitical issues hike costs 40% from non-China optimized sources.
• Limited Customization: No OEM options force generic buys, missing 15% formulation efficiency.
