5-Keto-D-gluconic acid potassium salt

5-Keto-D-gluconic acid potassium salt

5-Keto-D-gluconic acid potassium salt (CAS Nos: 5447-60-9; 91446-96-7) is the potassium salt form of 5-keto-D-gluconic acid, a ketoacid derivative of D-gluconic acid. It appears as a white to off-white crystalline powder, soluble in water up to approximately 50 mg/mL, making it suitable for aqueous-phase applications. Its molecular formula is C6H9KO7, with a molecular weight of 232.23 g/mol.

This compound is primarily produced by biotransformation using acetic acid bacteria species such as Gluconobacter oxydans, which oxidize glucose into various keto-D-gluconates, including 5-keto-D-gluconic acid potassium salt. It plays an important role as an intermediate in biochemical and industrial processes, notably as a precursor to tartaric acid, which is widely used in food and pharmaceutical industries.

The potassium salt is noted for its stability under normal conditions if stored refrigerated at 2-8 °C. It has low volatility and no significant reactive hazards under typical handling conditions. Safety measures suggest standard laboratory protective equipment to minimize skin and eye irritation risks.

Key properties and uses:

This compound is significant in both research and industrial biotechnology, especially in sustainable production processes of organic acids and their derivatives.creative-biolabs+4
