Description

6-o-Phenylascorbic Acid is a chemically modified derivative of ascorbic acid (Vitamin C) where a phenyl group is attached at the 6-O position. This structural modification enhances its stability and alters its redox properties, making it a valuable intermediate for advanced synthesis and a potent antioxidant in specialized applications. It is primarily utilized by R&D chemists and manufacturers in the pharmaceutical, cosmetic, and fine chemical industries for developing novel compounds and stabilizing sensitive formulations.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates and prodrugs, particularly those requiring enhanced stability.
• Cosmetic Antioxidant: Used in high-end skincare and anti-aging formulations for its potent and stable antioxidant properties.
• Biochemical Research: Serves as a tool compound in studies of oxidative stress, enzyme inhibition, and cellular protection mechanisms.
• Food & Beverage Additive (R&D Grade): Investigated for use as a specialized preservative and antioxidant in functional foods and beverages.
• Polymer Stabilizer: Acts as an antioxidant additive in plastics and coatings to prevent degradation during processing and extend product life.
• Reference Standard: Used as an analytical standard in quality control laboratories for HPLC and other chromatographic methods.

Quality Control

Our 6-o-Phenylascorbic Acid is produced under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
