Description

5-Hydroxyflavone is a naturally occurring flavonoid derivative, recognized for its role as a key chemical scaffold and intermediate in organic synthesis. This compound matters for its utility in developing novel pharmaceutical agents and bioactive molecules, particularly in research focused on antioxidant and enzyme-inhibitory activities. It is primarily needed by manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and fine chemical sectors seeking high-purity building blocks for advanced synthesis.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of more complex flavonoid-based drugs and therapeutic agents.
• Biochemical Research: Used as a standard or reference compound in studies investigating antioxidant mechanisms, enzyme inhibition (e.g., kinases, cyclooxygenases), and structure-activity relationships (SAR).
• Nutraceutical Development: Acts as a starting material for the production of specialized dietary supplements and health-promoting ingredients.
• Fine Chemical Synthesis: Employed in organic synthesis to create novel chemical entities for material science and agrochemical research.
• Cosmetic Ingredient Research: Investigated for potential use in skincare formulations due to the bioactive properties associated with the flavonoid structure.

Quality Control

Our 5-Hydroxyflavone is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by FT-IR and melting point determination. We provide Certificates of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

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 light-sensitive and easily oxidized nature, prolonged exposure to light and air should be avoided. For long-term storage, consider an inert atmosphere.
