Sucrose Acetate Isobutyrate (MF: C40H62O19 MW: 846.92), is a mixed ester compound formed from sucrose, 2 molecules of acetic acid, and 6 molecules of isobutyric acid. It is a colorless to pale yellow viscous liquid with no distinctive odor. It is insoluble in water but readily soluble in organic solvents such as ethanol, esters, and acetone. The molecule contains 8 ester groups and is chemically stable, serving as a key raw material for food additives, carrier for emulsified flavorings, and plasticizers.
