Докладно

Aldehyde C-14 is a name of gamma-undecalactone. It is a lactone, not an aldehyde.

Chemistry

Gamma-undecalactone is an 11-carbon gamma-lactone with a five-membered cyclic ester ring and an n-heptyl side chain. Its molecular formula is C11H20O2. Its IUPAC name is 5-heptyloxolan-2-one. It is soluble in alcohol, most fixed oils and propylene glycol, and insoluble in glycerol and in water.

Uses and regulation

Lactones contribute significantly to the flavor of fruit and of dairy products, and are therefore used as flavors and fragrances. Gamma-undecalactone is among the lactones named in that role. It is added to food as a flavoring agent or adjuvant. In cosmetic products it serves for masking and as a solvent. It is a REACH registered substance under the name undecan-4-olide.
