Description

2,3-Diketo-L-Gulonic Acid is a key intermediate in the biosynthesis of ascorbic acid (Vitamin C). This compound matters for its critical role in synthetic and enzymatic pathways, serving as a direct precursor in the Reichstein process and modern fermentation methods for Vitamin C production. It is essential for manufacturers in the pharmaceutical, nutraceutical, and food fortification industries who require high-purity intermediates for reliable and scalable synthesis.

Application

• Primary Intermediate for Vitamin C Synthesis: The most significant application is as the direct precursor in the commercial production of L-ascorbic acid (Vitamin C) via both chemical and biotechnological routes.
• Pharmaceutical Active Ingredient Intermediate: Used in the synthesis of high-purity ascorbic acid for pharmaceutical formulations, injections, and tablets.
• Nutraceutical and Dietary Supplement Production: A critical raw material for manufacturing Vitamin C used in supplements, multivitamins, and health products.
• Food and Beverage Fortification: Serves as a source material for food-grade Vitamin C, used as an antioxidant and nutrient additive in beverages, processed foods, and infant formula.
• Biochemical Research: Employed in enzymatic studies and metabolic pathway research related to carbohydrate metabolism and antioxidant systems.
• Cosmetic Ingredient Synthesis: Used in the production of ascorbic acid derivatives, such as ascorbyl palmitate, which are valued antioxidants in skincare and cosmetic formulations.

Quality Control

Our 2,3-Diketo-L-Gulonic Acid is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for pharmaceutical applications. Quality is verified through comprehensive analytical testing including HPLC, IR, and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

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). This product is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed after opening to minimize exposure to air and moisture. For long-term storage, consider using an inert atmosphere.
