Description

D-Galactono-1,4-Lactone is a key biochemical intermediate and chiral building block, essential for research and synthesis in advanced life sciences. Its primary commercial value lies in its role as a direct precursor in the enzymatic production of L-ascorbic acid (Vitamin C) and other bioactive compounds. This high-purity material is critical for pharmaceutical development, nutritional research, and specialized organic synthesis where precise stereochemistry is required.

Application

• Vitamin C Synthesis: A crucial enzymatic precursor in the commercial and research-scale biosynthesis of L-ascorbic acid.
• Pharmaceutical Intermediates: Serves as a chiral synthon for the development of glycoconjugates, glycomimetics, and other therapeutic agents.
• Biochemical Research: Used in studies of carbohydrate metabolism, enzyme kinetics (specifically galactonolactone dehydrogenase), and cellular redox processes.
• Nutraceutical & Cosmetic Ingredients: Employed in the research and development of advanced antioxidant formulations and skin health products.
• Food Science: Applied in research related to natural sweetener modification and food preservation mechanisms.
• Diagnostic Reagents: Utilized in the formulation of specialty reagents for clinical diagnostics and assay kits.

Quality Control

Our D-Galactono-1,4-Lactone is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and optical rotation, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) documenting all critical parameters 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 sealed under anhydrous conditions to prevent product degradation.
