Description

Syringetin-3-Galactoside is a specialized flavonoid glycoside compound, a key phytochemical derived from various plant sources. This high-purity standard is essential for research and development in the nutraceutical and pharmaceutical sectors, where precise chemical reference materials are critical. It is primarily sought by analytical laboratories, ingredient manufacturers, and R&D teams focused on natural product chemistry, antioxidant research, and the development of standardized botanical extracts.

Application

• Analytical Reference Standard: Used as a high-purity standard for the qualitative and quantitative analysis (e.g., HPLC, LC-MS) of plant extracts and complex botanical matrices.
• Nutraceutical Research: Serves as a key marker compound for the standardization and quality control of dietary supplements containing flavonoid-rich ingredients like pine bark or grape seed extracts.
• Pharmaceutical R&D: Investigated for its potential bioactive properties, including antioxidant, anti-inflammatory, and cardioprotective effects, in preclinical studies.
• Cosmeceutical Formulations: Incorporated into advanced skincare product research for its potential antioxidant and skin-protective benefits against environmental stressors.
• Food & Beverage Science: Used in studies to assess the flavonoid content, authenticity, and health-promoting value of foods and beverages like wines and fruit juices.
• Academic & Institutional Research: A vital reagent for universities and research institutions studying plant biochemistry, metabolic pathways, and the structure-activity relationships of flavonoids.
