Product Description
Isopropyl cinnamate (propan-2-yl (E)-3-phenylprop-2-enoate, C12H14O2) is a cinnamic acid ester belonging to the same family as methyl, ethyl and propyl cinnamate. It is insoluble in water and soluble in alcohol and oils.
In flavor and fragrance formulations it contributes balsamic, sweet and fruity notes, rounding out berry, peach and tropical fruit accords and adding warmth to amber and oriental fragrance bases.
Compared with methyl or ethyl cinnamate, the branched isopropyl ester has a higher boiling point and a softer, drier balsamic character, which helps the note persist longer and blend more smoothly in a formula.
For procurement, check assay and isomer content (trans form), appearance, acid value and refractive index against the specification. For food use, confirm the grade meets the applicable flavoring regulations, such as 21 CFR 172.515 in the US.

Frequently Asked Questions
How does isopropyl cinnamate differ from ethyl cinnamate?
Both are cinnamic acid esters with fruity, balsamic odors. The isopropyl ester has a higher boiling point and a softer, drier balsamic character, so it tends to last longer in a formula, while ethyl cinnamate is sweeter and more diffusive.
What should I check before using it in food flavors?
Confirm that the grade and documentation meet the flavoring regulations of the target market, for example FEMA 2939 / 21 CFR 172.515 in the US, and review assay and impurity results on the COA.
How should isopropyl cinnamate be stored?
Store tightly closed at room temperature, away from light and heat. The material may polymerize on prolonged storage and become cloudy or more viscous, so check appearance before use.
