Description

1-o-Methylascorbic Acid is a stable, fat-soluble derivative of Vitamin C (L-ascorbic acid), where a methyl group is introduced at the oxygen position. This structural modification significantly enhances its stability against oxidation and moisture while retaining valuable antioxidant properties, making it a crucial ingredient for advanced formulations. It is primarily sought after by manufacturers in the cosmetics, personal care, and pharmaceutical industries for developing high-performance, shelf-stable products.

Application

• Cosmetic & Skincare Actives: A key ingredient in anti-aging serums, creams, and lotions for its stable antioxidant and skin-brightening properties.
• Pharmaceutical Intermediates: Used in the synthesis of more complex pharmaceutical compounds requiring a stabilized ascorbic acid moiety.
• Nutraceutical Formulations: Incorporated into advanced dietary supplements where enhanced stability in final product matrices is required.
• Hair Care Products: Added to treatments and shampoos to protect hair from oxidative stress and environmental damage.
• Research & Development: Serves as a standard or reagent in biochemical and pharmacological research studying antioxidant mechanisms.
• Functional Food Additives: Potential use as a stable antioxidant preservative in specific food-grade applications.

Quality Control

Our 1-o-Methylascorbic Acid is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, identity confirmation by IR spectroscopy, and residual solvent analysis to ensure it meets stringent specifications for high-grade applications. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation. For long-term storage, consider using an inert atmosphere to minimize oxidation.
