Description and Uses
Isopropyl isobutyrate has an intense, fruity, ether-like odor. May be prepared by boiling isobutyryl chloride and isopropyl alcohol.
Isopropyl Isobutyrate is a useful reactant in organic synthesis.
It is also used occasionally in flavor compositions as a modifier for higher and lower
alkylbutyrates in Pineapple, Apricot, Pear and
in certain types of Citrus complex flavors. It is
the lightest and freshest tasting of all four
Propylbutyrates.
The concentration of this ester in finished
products will vary from 10 to 100 ppm.
