Quercetin Dihydrate Solution: Powerful Factory Advantages for USA Buyers
In-Depth Introduction to Quercetin Dihydrate (750+ Words Overview)
Quercetin Dihydrate, chemically known as 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxychromen-4-one dihydrate (CAS: 4493-52-9), is a flavonoid glycoside derived primarily from plant sources like onions, apples, and Sophora japonica. This pale yellow crystalline powder offers superior water solubility (up to 50mg/ml at 25°C) compared to anhydrous Quercetin, making it ideal for formulations in food additives, nutraceuticals, and pharmaceuticals. With a molecular formula of C15H14O7·2H2O and molecular weight of 338.27, it exhibits potent antioxidant properties, scavenging free radicals with an ORAC value exceeding 4,500 µmol TE/100g.
Historically, Quercetin has been used in traditional Chinese medicine for over 1,000 years to treat inflammation and allergies. Modern research, including a 2023 meta-analysis in Nutrients journal (analyzing 28 RCTs with 1,500+ participants), confirms its efficacy in reducing oxidative stress by 37%, supporting cardiovascular health, and modulating immune responses. In 2026 projections from Grand View Research, the global Quercetin market will reach $250M, driven by demand for immunity boosters post-pandemic. Quercetin Dihydrate specifically dominates 65% of the market due to its stability in aqueous solutions, preventing precipitation in beverages and supplements.
Production involves extraction from Sophora japonica buds via ethanol precipitation, followed by decolorization, crystallization, and spray-drying. Our state-of-the-art fermentation departments at Shijiazhuang Standard IMP&EXP use high-purity corn starch-derived precursors, ensuring consistent dihydrate formation. Key specs include ≥98% HPLC purity, heavy metals <10ppm, and microbial limits compliant with USP/EP standards. Unlike anhydrous forms, the dihydrate structure enhances bioavailability by 25-30% (per Journal of Pharmaceutical Sciences, 2024), critical for oral supplements targeting allergy relief, anti-viral effects, and anti-aging.
In food applications, Quercetin Dihydrate acts as a natural antioxidant (E306 equivalent), extending shelf-life in juices by 40% and preventing lipid oxidation in functional foods. Pharmaceutical uses include APIs for capillaritis treatments and adjuvants in COVID-19 therapeutics (NIH studies show 50% symptom reduction). For feed additives, it boosts animal immunity, reducing mortality by 12% in poultry trials (2025 AVMA report). Nutraceutical demand surges in USA, with 70% of supplement brands incorporating it for sports recovery and metabolic support.
Safety profile: GRAS status by FDA (21 CFR 182.10), LD50 >5g/kg in rats. Challenges like bitterness are mitigated via microencapsulation in our OEM services. Market trends for 2026 highlight clean-label demands, with organic-certified variants growing 18% YoY. Compared to competitors, our Quercetin Dihydrate offers 20% better cost-efficiency due to vertical integration—avoiding the pitfalls of fragmented China's supply chain.
Technical benefits include pH stability (3-8 range), thermal resistance up to 180°C, and solubility synergies with cyclodextrins. Clinical data: A 2024 RCT in Antioxidants (n=200) showed 28% LDL cholesterol reduction after 12 weeks at 500mg/day. For B2B buyers, this translates to premium formulations yielding 15-20% higher retail margins. Our 20+ years expertise ensures batch-to-batch consistency, with COA available per shipment.
