Sucralose yog ib qho ntawm halogenated sucrose derivatives, tseem hu ua "super qab zib sucrose". Nws lub npe tshuaj yog 4,1 ', 6' - trichloro -4, 1 ', 6' - trimethoxygalactose. Nws yog ib qho khoom qab zib muaj zog nrhiav tau los ntawm xibfwb Hough L hauv xyoo 1970s. Nws cov mis molecular yog C12H19O8Cl3, thiab nws qhov hnyav molecular yog 397.64.
Sucralose, hu ua sucralose, yog siv los tsim cov khoom qab zib tsis muaj calorie tsis muaj zog, uas tsis muaj ntxhiab thiab hygroscopic. Cov khoom muaj thermal stability, yog heev soluble nyob rau hauv dej, thiab yuav soluble nyob rau hauv ethanol, methanol thiab lwm yam organic solvents. Solubility yog 28.2g ntawm chav tsev kub ntawm 28 degree. Nws muaj kev ruaj ntseg nyob rau hauv ib puag ncig lub teeb, thermal ib puag ncig thiab pH hloov. Cov tshuaj aqueous ntawm sucralose yog qhov tseeb thiab pob tshab, pH ntawm cov tshuaj aqueous yog 5, thiab kev ruaj ntseg yog siab, thiab yuav tsis muaj tshuaj hloov pauv tom qab khaws cia rau ntau tshaj 1 xyoos. Cov siv lead ua yuav tsis hloov tshuaj tom qab khaws cia li ntawm 4 xyoos, thiab qhov qab zib yuav tsis hloov nyob rau hauv qhov kub thiab txias.
