Acesulfame potassium is a calorie-free artificial sweetener, also known as Acesulfame K or Ace K (K being the symbol for potassium), and marketed under the trade names Sunett and Sweet One. In the European Union, it is known under the E number (additive code) E950. It was discovered accidentally in 1967 by German chemist Karl Clauss at Hoechst AG (now Nutrinova). In chemical structure, acesulfame potassium is the potassium salt of 6-methyl-1,2,3- oxathiazine-4(3H)-one 2,2-dioxide. It is a white crystalline powder with molecular formula C4H4KNO4S and a molecular weight of 201.24.Acesulfame KAcesulfame potassiumAcesulfame-kE950H 733293Hoe 095KC4H5KNO4S202.25201.957635204potassium 6-methyl-3,4-dihydro-1,2λ⁶,3-oxathiazine-2,2,4-trionepotassium acesulfame55589-62-3[K+].CC1=CC(=O)NS(=O)(=O)O1InChI=1S/C4H5NO4S.K/c1-3-2-4(6)5-10(7,8)9-3;/h2H,1H3,(H,5,6);/q;+1WBZFUFAFFUEMEI-UHFFFAOYSA-N belongs to the class of organic compounds known as organic sulfuric acids and derivatives.
