Quercetin 95% CAS 117-39-5: High-Purity Flavonoid for Premium Nutraceutical & Skincare Formulations

Product Description

Quercetin (CAS 117-39-5) is a naturally occurring flavonoid belonging to the polyphenolic phytochemicals group, widely distributed in fruits, vegetables, and medicinal plants. Chemically known as 3,3',4',5,7-pentahydroxyflavone, quercetin is one of the most extensively studied flavonoids for its biological activities and potential health applications.

Our quercetin is available in a 95% purity grade (HPLC-verified), sourced from natural plant materials and processed through controlled extraction to ensure consistent quality, batch-to-batch reliability, and full regulatory documentation support.

Key Product Specifications

Mechanism of Action for High Purity Quercetin Powder

Quercetin functions through multiple pathways with potential relevance to various physiological systems:

Antioxidant Support — Neutralizes free radicals and chelates transition-metal ions, supporting the body's natural defense mechanisms against oxidative stress

Inflammatory Response Modulation — Modulates inflammatory signaling pathways, including NF-κB inhibition, supporting healthy inflammatory balance

Enzyme Inhibition — Acts as a stimulator of SIRT1 and inhibitor of PI3K with documented activity

Nrf2 Pathway Activation — Upregulates nuclear Nrf2 protein and downstream antioxidant enzymes (SOD, HO-1, GCLC), supporting cellular antioxidant defense

The Main Applications for Quercetin 95% CAS 117-39-5 Powder

Nutraceuticals & Dietary Supplements

Research & Reference Standards

The 95% grade can serve as a research-grade material for analytical reference and biological studies.
 

Formulation Considerations

For Capsules and Tablets:

• Blend directly with appropriate excipients (microcrystalline cellulose, etc.)

• Ensure uniform mixing for consistent dosing

• Dissolution enhancement: lactose monohydrate (at 10% concentration) has been shown to improve quercetin tablet dissolution time, suggesting stable tablet formulations can be developed with appropriate excipient selection

For Liquid Formulations:

• Pre-dissolve in ethanol or DMSO before incorporating into aqueous systems

• Alternative approaches: use of biocompatible solvents such as choline-tryptophan ionic liquids has been shown to enhance quercetin solubility in aqueous systems

• Protect from light using amber packaging

For Cosmetic Formulations:

• Incorporate into the oil phase or use appropriate solubilizers

• Consider advanced delivery systems (liposomes, nanoparticles) to enhance bioavailability
