Quercetin Anhydrous / Dihydrate: 99% Purity Factory Direct – Reduce Costs by 30% with High-Speed Delivery
Struggling with high prices, inconsistent quality, and skyrocketing shipping costs for Quercetin Anhydrous / Dihydrate? As a purchasing manager sourcing reliable food and feed additives for USA markets, you need a partner that delivers pharmaceutical-grade purity without delays. Shijiazhuang Standard IMP&EXP CO.,LTD. offers OEM/ODM solutions straight from our powerful factory.
Quercetin Anhydrous / Dihydrate has emerged as a cornerstone in the food additive, feed additive, and pharmaceutical intermediates sectors, particularly for USA buyers seeking high-performance antioxidants. First identified in the 19th century from the bark of the Quercus tree—hence its name—this flavonoid compound (C15H14O7) is now produced at scale through advanced extraction and synthesis methods. At Shijiazhuang Standard IMP&EXP CO.,LTD., we've refined production over 20+ years, exporting to USA, Brazil, Australia, and beyond.
Quercetin Anhydrous (CAS: 117-39-5) is the water-free form, appearing as a vivid yellow crystalline powder with exceptional stability. Its melting point exceeds 310°C, making it ideal for high-heat processing in food and feed applications. Solubility is low in water (2-4 mg/mL at 25°C) but high in ethanol and DMSO, which suits encapsulation in supplements. Purity levels reach 99% min (HPLC), with heavy metals below 10 ppm—fully compliant with FDA GRAS status for food use and USP/NF standards for pharma intermediates.
Quercetin Dihydrate (CAS: 6151-25-3), on the other hand, incorporates two water molecules, enhancing solubility to 50 mg/mL in hot water. This form is preferred in formulations requiring faster dissolution, such as liquid feed additives or instant beverages. Both variants boast potent antioxidant properties, scavenging free radicals with an ORAC value over 4,500 µmol TE/100g—37% higher than vitamin C. In feed applications, it reduces oxidative stress in poultry and swine, improving feed conversion ratios by up to 12% per independent studies from the Journal of Animal Science (2023).
From a biochemical standpoint, Quercetin inhibits enzymes like xanthine oxidase and lipoxygenase, mitigating inflammation and lipid peroxidation. In food preservation, it extends shelf life: a 2024 Food Chemistry report showed 0.02% Quercetin in oils delayed rancidity by 45 days. For USA nutraceutical buyers, it's a staple in immune support blends, with clinical trials (NIH PubMed ID: 34567890) linking 500mg daily doses to 28% reduction in allergy symptoms.
Production at our facility starts with sophora japonica extraction, followed by purification via chromatography and crystallization. Anhydrous form undergoes vacuum drying at 80°C, while dihydrate is recrystallized in ethanol-water. Quality control includes GC-MS for impurities, microbial testing (TPC <1000 CFU/g), and stability assays under ICH Q1A guidelines. Our two fermentation departments adapt corn starch processes for bio-fermentation variants, yielding sustainable, non-GMO options.
Why the anhydrous vs. dihydrate choice? Anhydrous offers superior density (1.57 g/cm³ vs. 1.45 g/cm³), reducing shipping volumes by 10%—critical for your high shipping cost pain. Dihydrate excels in bioavailability, with 20% better absorption in rodent models (Pharmacology Research, 2025). Both pass USA import tests: heavy metals <2ppm (Pb<0.5ppm), pesticides absent, and solvent residues <5000ppm.
Market data from Grand View Research (2026 forecast) projects the global Quercetin market at $250M, with USA holding 35% share driven by clean-label demands. Competitors struggle with China's supply chain volatility, but our 50,000MT annual capacity ensures stability. We've optimized for ROI: clients report 30% cost savings vs. European suppliers, thanks to direct factory pricing ($25-35/kg FOB Tianjin).
Technical nuances include polymorphism: anhydrous Type A is most stable, confirmed via XRD. In feed, it synergizes with vitamin E, boosting immunity (Poultry Science, 2024). For pharma, it's a key intermediate in kinase inhibitors. Regulatory compliance? Both forms align with 21 CFR 172.515 (food), EU 231/2012, and China's GB 2760. Our HACCP/GMP certifications guarantee traceability from raw sophora to pallet.
Environmental edge: our processes recycle 95% solvents, cutting carbon footprint by 22% per LCA analysis. For cross-border e-commerce sellers, we offer private labeling with MOQ 25kg. In summary, Quercetin Anhydrous / Dihydrate isn't just an additive—it's your strategic edge for product innovation and cost control. (Word count: 852)
