In short
Fructone (ethyl acetoacetate ethylene ketal) has a fresh, sweet apple and pineapple note.
What Fructone smells like
Fructone (apple ketal, ethyl methyl dioxolane acetate) has a fruity, apple-like smell with pineapple, strawberry and woody aspects reminiscent of pine. IFF describes it as strong, fruity, exotic and apple-like with pineapple and strawberry notes; ChemicalBook as strong and fruity, apple-like with a slight green edge; a distributor finds a winey character and cooked-strawberry nuances, with notable tenacity for a fruity material. It does not occur in nature.

What makes Fructone distinctive
A sweet, rounded apple-pineapple that lasts — a ketal rather than an ester, so it is more tenacious than the fruity esters, with a woody-pine undertone.
How Fructone is used
Used very widely to give body to fruit notes — apple, strawberry, pineapple, kiwi and grape — in fine and functional fragrance.
Typical role: modifier (used in small amounts to change the character of a blend); blender (smooths the joins between other materials).
How Fructone differs from similar materials
- Fraistone
- Fraistone, a related ketal, is tarter, greener and more strawberry-plum, with an anisic note; Fructone is sweeter, more apple-pineapple and woody. (compared directly by a cited source)
- Ethyl 2-Methylbutyrate
- Ethyl 2-methylbutyrate is fresher, greener and more diffusive; Fructone is sweeter, rounder and longer-lasting.
- Ethyl Acetoacetate
- Ethyl acetoacetate, from which Fructone is made, is a lighter, ethereal green apple with a rum note; Fructone is sweeter and more tenacious.
- Fructalate
- Fructalate is a fruity diester with raspberry and pineapple beside the apple, more ethereal and longer-lasting; Fructone is the sweeter strawberry-apple ketal.
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
