sinensal

Found in 1 ingredient across the CompKitchen flavor graph.

Ambiguous name

“sinensal” does not identify one molecule. Denotes either alpha- or beta-sinensal. Both are C15H22O sesquiterpene aldehydes of citrus, and the distinction is not academic: beta-sinensal is the character-impact aroma compound of sweet orange, while alpha-sinensal is used to tell mandarins from oranges (Goh et al. 2022, PLoS ONE 17(4): e0267007, found it at 0.7% or more in mandarins and under 0.05% in oranges). PubChem resolves the bare name to beta-sinensal, but our source did not state which was measured, so we do not assign one.

Could be any of

alpha-sinensal · CAS 17909-77-2 · C15H22O · PubChem 5281534

beta-sinensal · CAS 60066-88-8 · C15H22O · PubChem 5281535

We assign no CAS number, structure or odour threshold to this entry. Guessing one would make the record look more certain than the evidence is.

Look up another compound — search by name, CAS number, PubChem CID, or FEMA #.

Measured impact first, then profile share

Every ingredient known to contain sinensal. Ingredients with a measured concentration come first, ranked by odour activity; the rest follow by how large a share of that ingredient's profile this molecule is. The figure beside each is how many different compounds that ingredient has in total — not the concentration of sinensal in it.
