Description

Potassium D-Gluconate Hydrate is a high-purity, water-soluble potassium salt of D-gluconic acid, widely recognized for its excellent bioavailability and compatibility. This compound serves as a superior source of bioavailable potassium in critical applications where chloride or other anions are undesirable. It is essential for manufacturers in the pharmaceutical, nutraceutical, and high-grade food industries seeking a reliable, non-irritating mineral fortifier and buffering agent. Its consistent quality makes it a trusted ingredient for formulating electrolyte solutions, dietary supplements, and specialized chemical intermediates.

Application

• Pharmaceutical Formulations: Used as a potassium source in electrolyte replenishers, intravenous solutions, and tablet formulations where a non-chloride salt is required.
• Nutraceuticals & Dietary Supplements: A key ingredient in mineral supplements, sports drinks, and health tonics due to its high bioavailability and mild taste.
• Food & Beverage Fortification: Employed as a nutrient additive and pH buffer in specialized food products, infant formula, and functional beverages.
• Biotechnology & Cell Culture Media: Acts as a component in defined media and buffer systems for microbial fermentation and cell culture processes.
• Chemical Synthesis: Serves as a mild, biodegradable sequestering agent and a starting material or intermediate in organic synthesis.
• Cosmetic & Personal Care: Utilized in formulations for skin conditioning and as a humectant in lotions and creams.
