Description

5-Keto-D-Gluconic Acid Potassium Salt is a key biochemical intermediate and a versatile organic salt. This compound is valued for its role in metabolic pathways and as a precursor in the synthesis of various fine chemicals and food additives. It is primarily sought by manufacturers in the pharmaceutical, food & beverage, and cosmetic industries for applications ranging from fermentation processes to formulation excipients.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and as a component in fermentation-based production of ascorbic acid (Vitamin C).
• Food & Beverage Additive: Functions as a pH regulator, sequestrant, and a precursor for other food-grade acids and flavor enhancers.
• Cosmetic & Personal Care: Employed in formulations as a skin-conditioning agent and a mild exfoliant due to its α-keto acid structure.
• Biochemical Research: Serves as a substrate or standard in enzymatic studies and metabolic pathway analysis.
• Industrial Fermentation: Acts as a key metabolite in microbial fermentation processes for the production of organic acids and other bio-based chemicals.
• Animal Nutrition: Utilized as a feed additive to support gut health and nutrient absorption.

Quality Control

Our 5-Keto-D-Gluconic Acid Potassium Salt is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical and food-grade applications. Certificates of Analysis (COA) are provided with every shipment and 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 opening to prevent absorption of atmospheric moisture.
