Acesulfame potassium (UK: /æsɪˈsʌlfeɪm/, US: /ˌeɪsiːˈsʌlfeɪm/ AY-see-SUL-faym or /ˌæsəˈsʌlfeɪm/), also known as acesulfame K or Ace K, is a synthetic calorie-free sugar substitute (artificial sweetener) often 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). 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 C
₄H
₄KNO
₄S and a molecular weight of 201.24 g/mol.
