Description and Uses

Isobutyl formate has a fruity, ether-like odor and a sweet taste reminiscent of rum. Isobutyl formate may be prepared from isobutyl alcohol and carbon monoxide in the presence of sodium isobutylate at 110°C and 400 atm.

Isobutyl Formate is a synthetic flavoring agent that is a stable, colorless liquid of fruity odor. storage should be in glass or tin containers. it is used in fruit flavors such as pear, raspberry, and other berry flavors with applications in beverages, ice cream, candy, and baked goods at 2–18 ppm.
