Description

L-Ascorbic Acid 2-Phosphate (Magnesium Salt Hydrate) is a stabilized, water-soluble derivative of Vitamin C, designed to overcome the inherent instability of ascorbic acid. This compound is critical for applications requiring a long-lasting, bioavailable source of Vitamin C that is resistant to oxidation and degradation. It is primarily utilized by manufacturers in the cosmetic, pharmaceutical, and nutraceutical industries for its superior stability and skin-brightening or antioxidant efficacy.

Application

• Cosmetic & Skincare Formulations: A key active ingredient in anti-aging serums, creams, and lotions for collagen synthesis, skin brightening, and antioxidant protection.
• Pharmaceutical Intermediates: Used in the synthesis of more complex pharmaceutical compounds requiring a stabilized Vitamin C precursor.
• Nutraceuticals & Dietary Supplements: Incorporated into advanced supplement formulations for enhanced bioavailability and shelf-life compared to standard ascorbic acid.
• Cell Culture Media: Serves as a stable source of Vitamin C in specialized cell culture and tissue engineering applications.
• Functional Food & Beverage Fortification: Used to fortify products where standard Vitamin C would degrade rapidly, ensuring label claim integrity.
• Research & Development: Employed in biochemical and pharmacological research as a stable analog of L-ascorbic acid.
