How we scored it

C13H22O3 226.3: pentyl-cyclopentanone core from cyclopentanone and pentanal, methyl acetate side chain from malonate/methanol; no natural-origin fragment. 0 / 226.3 = 0.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Made by condensing cyclopentanone with pentanal, isomerising, adding a malonate unit, decarboxylating and esterifying with methanol, all from petrochemical building blocks. Isolation from natural jasmonate sources is not used for commercial supply.

In plain English

Methyl dihydrojasmonate (Hedione), a fragrance material with a fresh, jasmine-like, slightly citrus scent. It is made synthetically from petrochemical building blocks, not extracted from jasmine.
