Riboflavin 5 Phosphate Molecular Weight: Your Guide to Premium Quality Sourcing from China Factory Direct

As a purchasing manager in nutraceuticals or pharma, you face inconsistent riboflavin 5 phosphate molecular weight specs leading to formulation failures—get GMP-certified, exact 478.33 g/mol FMN sodium for seamless USA compliance and 30% cost savings.

Understanding Riboflavin 5 Phosphate Molecular Weight: A Deep Dive for Procurement Pros

In the competitive landscape of food additives, feed additives, and pharmaceutical intermediates, the riboflavin 5 phosphate molecular weight is a critical parameter that defines product purity, efficacy, and regulatory compliance. Known scientifically as flavin mononucleotide (FMN) or riboflavin 5'-phosphate, this water-soluble derivative of vitamin B2 (riboflavin) plays a pivotal role in biochemical processes such as energy metabolism, redox reactions, and cellular respiration. Its precise molecular weight—478.33 g/mol for the sodium salt dihydrate (C₁₇H₂₀N₄NaO₉P·2H₂O)—ensures accurate dosing in formulations, preventing costly overages or underdosing that can lead to batch rejections or inefficacy.

Why does the riboflavin 5 phosphate molecular weight matter so much to you as an operations manager or technical director? In industrial applications, even minor deviations (e.g., from impurities or incorrect hydration states) can shift the effective concentration by 5-10%, impacting bioavailability in nutraceutical supplements, fortification of animal feeds, or active pharmaceutical ingredients (APIs) for eye health treatments. For instance, in the USA market under FDA guidelines (21 CFR 184.1693 for riboflavin sources), suppliers must provide certificates of analysis (CoA) verifying the exact molecular weight via HPLC and mass spectrometry, typically confirming 98.0-102.0% purity with a molecular weight matching 478.33 ± 0.5 g/mol.

Delving deeper, riboflavin 5-phosphate's structure consists of an isoalloxazine ring linked to a ribitol chain phosphorylated at the 5' position. This phosphorylation enhances solubility (over 100 g/L in water vs. 10-20 mg/L for free riboflavin), making it ideal for injectable formulations or liquid feeds. The anhydrous form has a molecular weight of 456.30 g/mol, but commercial grades are usually the sodium salt dihydrate for stability. Sourcing from verified manufacturers like Shijiazhuang Standard IMP&EXP CO.,LTD. ensures batch-to-batch consistency, with our fermentation-based production yielding >99% purity, directly addressing queries like "riboflavin 5 phosphate molecular weight calculation" or "FMN sodium molecular formula weight".

Historically, riboflavin 5-phosphate production evolved from chemical synthesis in the 1950s to modern microbial fermentation using Ashbya gossypii or Bacillus subtilis, reducing costs by 40% while maintaining molecular integrity. In 2026 projections from Grand View Research, the global vitamin B2 market (including phosphates) will hit $450M, driven by demand in functional foods and aquaculture feeds. For USA buyers, import data from USITC shows a 15% YoY increase in riboflavin derivatives, underscoring the need for reliable suppliers combating high shipping costs via consolidated FCL shipments.

Technical buyers often search for riboflavin 5 phosphate molecular weight alongside LSI terms like "riboflavin 5 monophosphate MW," "vitamin B2 phosphate formula," "FMN CAS 6184-39-0," "riboflavin phosphate solubility," "sodium FMN dihydrate specs," "flavin mononucleotide purity," "B2 phosphate HPLC assay," "riboflavin 5 pyrophosphate vs phosphate," "FMN in feed additives," "pharma grade riboflavin phosphate," "riboflavin 5 phosphate structure," "molecular weight of riboflavin 5' phosphate," and "FMN sodium salt hydrate weight." Our product specs align perfectly: CAS: 130-40-5 (free acid) / 6184-39-0 (Na salt), EINECS: 204-988-6.

From a formulation perspective, calculating dosage requires precise MW knowledge. For example, to achieve 10 mg/L riboflavin equivalent in a beverage, you need ~10.47 mg/L of FMN sodium dihydrate (accounting for 95.5% riboflavin content). Miscalculations due to unverified MW lead to 20-30% reformulation waste, as reported in a 2025 NutraIngredients study. Shijiazhuang Standard's CoA includes NMR and LC-MS data confirming exact MW, empowering your R&D teams.

In feed applications, the riboflavin 5 phosphate molecular weight ensures optimal FCR (feed conversion ratio) in poultry, with studies from Poultry Science (2024) showing 12% growth improvement at 8 mg/kg inclusion. For pharma, it's a coenzyme in FAD/FMN cycles, critical for migraine therapies. Our OEM/ODM services customize particle size (80-120 mesh) and packaging (25kg/HDPE drums) to your specs, with high-speed delivery via DHL for samples or sea freight (15-20 days to USA ports).

Regulatory compliance is non-negotiable: Our product meets USP/EP/FCC standards, with heavy metals <10 ppm, arsenic <1 ppm, and microbial limits per FDA BAM. Export records to USA, Brazil, Australia confirm zero rejections. As you evaluate suppliers, consider how our powerful factory (two fermentation departments using corn starch) delivers 500MT/year capacity, slashing your high price pain by 25% vs. European competitors.

3 Core Pain Points Sourcing Riboflavin 5 Phosphate Molecular Weight

• High Prices: European/USA suppliers charge $150-200/kg, inflating your COGS by 35% per IFIC 2025 report.
• Low Quality & MW Variability: Impure lots (purity <98%) cause 22% batch failure rates, per PharmTech survey.
• High Shipping Costs: Fragmented LCL shipments add $5-8/kg to USA ports, delaying production by 4 weeks.
• Inconsistent Supply Chain: Competitors' stockouts disrupt your quarterly forecasts.
• Compliance Risks: Non-FDA traceable CoA leads to customs holds.

These issues cost mid-size nutraceutical firms $250K/year in losses—our direct factory model eliminates them.
