Sucralose is a potent non-caloric sweetener, also known by the trade name Splenda. It is 500–700 times sweeter than sucrose, making it roughly twice as sweet as saccharin. It is manufactured by the selective chlorination of sucrose, by which three of sucrose's hydroxyl groups are substituted with chlorine atoms to produce 1,6-dichloro-1,6-dioxy-β-D-fructo-furanosyl 4-chloro-4-deoxy-α-D-galactopyranoside. Unlike aspartame, it is stable under heat and over a broad range of pH conditions, and can be used in baking, or in products that require a long shelf life.
