Description

Sulfuric Acid 3',4',5,7-Tetrahydroxyflavone-3-Yl Ester is a chemically modified flavonoid derivative, specifically an ester of sulfuric acid and a tetrahydroxyflavone core. This compound is valued for its enhanced solubility and stability profile compared to its parent flavonoid, making it a crucial intermediate for advanced research and development. It is primarily sought by the pharmaceutical, nutraceutical, and specialty chemical industries for applications in drug discovery, biochemical research, and the synthesis of novel bioactive compounds.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates targeting inflammation, oxidative stress, and metabolic disorders.
• Biochemical Research: Used as a standard or probe in enzymatic studies, receptor binding assays, and metabolic pathway analysis due to its specific flavonoid structure.
• Nutraceutical Development: Serves as a precursor for developing advanced, bioavailable flavonoid-based supplements and functional food ingredients.
• Cosmetic Actives: Investigated for use in premium skincare formulations for its potential antioxidant and skin-protective properties.
• Chemical Synthesis: An important specialty intermediate for organic chemists creating libraries of flavonoid derivatives for structure-activity relationship (SAR) studies.
• Analytical Reference Standard: Employed as a high-purity certified reference material (CRM) for quality control and analytical method development in laboratories.

Quality Control

Our Sulfuric Acid 3',4',5,7-Tetrahydroxyflavone-3-Yl Ester is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or production standards. Custom purity grades, including research and pharmaceutical intermediates, are available.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation. For long-term storage, consider using desiccants.
