Description
Methyl 2-octynoate (also known as methyl 2-caprylate) is a kind of
fatty acid ester formed by the esterfication between methanol and 2
-octynoate. It is a kind of useful flavor and fragrance agent.

Description
Methyl 2-octynoate has an odor similar to violets on dilution, and
if concentrated, a powerful and unpleasant odor. It has a wineberry
flavor (muscatel). It may be prepared from heptaldehyde via
heptyne and heptyne carboxylic acid; the acid is subsequently
esterified.
Chemical Properties
Colorless liquid; strong violet-type odor. Sol-uble in most fixed oils and mineral oil; soluble infive parts of 70% alcohol. Combustible.

General Description
Methyl 2-octynoate has been quantitated as suspected allergen in cosmetic products by headspace-programmed temperature vaporization-fast gas chromatography-quadrupole mass spectrometry. It participates in nickel-catalyzed carbocyclization of 2-iodoacetophenone to yield a 2,3-disubstituted indenol.
Trade name
Folione® (Givaudan).

Safety Profile
Moderately toxic by
ingestion and skin contact. A moderate skin
and eye irritant. A combustible liquid. When
heated to decomposition it emits acrid
smoke and irritating fumes.
