| Acesulfame Potassium | Acesulfame Potassium. CAS No. 55589-62-3. Product ID: PE-0484. Molecular formula: C4H4KNO4S. Mole weight: 201.24. Category: Sweetening agent. Product Keywords: Pharmaceutical Excipients; Excipients for Solid Dosage Form; Acesulfame Potassium; Sweeteners Excipients; Sweetening agent; C4H4KNO4S; 55589-62-3; 55589-62-3. UNII: NA. Chemical Name: 6-Methyl-1, 2, 3-oxathiazin-4(3H)-one-2, 2-dioxide potassium salt. Grade: Pharmceutical Excipients. Administration route: Oral. Dosage Form: Oral preparations. Stability and Storage Conditions: Acetylsul panpotassium has good stability. Stored in bulk at room temperature for many years without signs of decomposition. The sweetness of aqueous solution (pH 3.0 - 3.5, 20°C) did not decrease for about two years. Although some decomposition after storage at 40°C for several months, it has good stability at temperature rise. Neither sterilization nor pasteurization affected the sweetness of acetylsulpanpotassium. Bulk products should be stored in airtight containers in a dry place. Source and Preparation: Acetylsul panpotassium is synthesized from tert-butyl acetoacetate and fluorosulfonyl isocyanate. The resulting product is converted to fluorosulfonyl acetoacetamide and cyclized into dioxythiazone cyclization in the presence of potassium hydroxide. Because this compound is strongly acidic, it can directly form potassium salt. Another route for the synthesis of acetylsulfamide be |  |
