Isoamyl Formate is a synthetic flavoring agent that is a moderately stable, colorless to light yellow liquid of pungent pear-plum odor, being soluble in most fixed oils, mineral oil, and propylene glycol. Storage should be in a glass or tin container. It is used in fruit flavors such as pear, plum, and peach for application in dessert gels, puddings, candy, and ice cream at 14–28 ppm.
ChEBI: The formate ester of isoamylol.
By reacting concentrated H2SO4 over a mixture of isoamyl alcohols and sodium formate.
Taste characteristics at 15 ppm: sharp green, apple and fruity with winey, fatty notes
The colourless liquid ester is soluble in 300 volumes of H2O and is soluble in common organic solvents. It is purified by repeated distillation using an efficient column at atmospheric pressure. [Beilstein 2 H 22, 2 I 18, 2 II 31, 2 III 43, 2 IV 30.]
