Description

5,6-Diacetoxy-L-Ascorbic Acid is a chemically modified, stabilized derivative of Vitamin C, where the 5 and 6 hydroxyl groups are acetylated. This modification enhances its stability against oxidation, making it a valuable intermediate for synthesizing high-value compounds in the pharmaceutical and cosmetic industries. It is particularly sought after by manufacturers of active pharmaceutical ingredients (APIs), advanced skincare formulations, and nutritional supplements requiring a more lipophilic and stable form of ascorbic acid.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of more complex Vitamin C derivatives and other active pharmaceutical ingredients (APIs).
• Cosmetic & Skincare Actives: Used in the production of stabilized Vitamin C derivatives for anti-aging, brightening, and antioxidant serums and creams.
• Nutritional Supplement Precursor: Serves as a protected intermediate in the manufacturing of specialized, high-bioavailability nutritional supplements.
• Biochemical Research: Employed as a reagent in enzymatic studies and research on antioxidant mechanisms and collagen synthesis.
• Food Fortification (Specialized): Potential use in developing stable, fat-soluble forms of Vitamin C for specific food and beverage applications.
