FDA regulates sucralose as an allowable artificial sweetener and food additive (more information available here: FDA LINK) identified as "a disaccharide that is made from sucrose in a five-step process that selectively substitutes three atoms of chlorine for three hydroxyl groups in the sugar molecule." The sweetness intensity for sucralose is 320 to 1000 times that of sucrose, depending on the food application (more information available here: FR LINK)
