General Description
Clear, colorless to yellowish liquid with a strawberry-like odor.
Reactivity Profile
Esters, such as 3-METHYL-3-PHENYLGLYCIDIC ACID ETHYL ESTER(77-83-8), react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Air & Water Reactions
Insoluble in water.
Fire Hazard
This chemical is probably combustible.
Chemical Properties
clear yellow liquid
Chemical Properties
Ethyl 3-Methyl-3-phenylglycidate exists as two optically
active pairs of cis- and trans-isomers; each isomer has a characteristic odor
. The commercial product is a racemic mixture of all four isomers and has
a strong, sweetish, strawberry odor. The cis/trans ratio obtained in the Darzens
condensation of acetophenone (R==CH3) and ethyl chloroacetate depends on the
base used in the reaction.
Chemical Properties
Ethyl methylphenylglycidate on dilution has a strong fruity odor suggestive of strawberry. It has a characteristic, slightly
acid taste reminiscent of strawberry.
Chemical Properties
Perennial, herbaceous plant; grows wild or cultivated in central–southern Europe, North America and Asia. The plant grows 10 to 20 cm (4 to 8 in.) in height and has thick rhizomes; radical leaves with long, small, white flowers blossoming from April to July; and fleshy, ovoidal, red berries covered with numerous achenes. The only part used is the berries. Strawberry has a sweet–sour taste and a characteristic odor.
Occurrence
Has apparently not been reported to occur in nature.
Definition
ChEBI: Phenylmethylglycidic ester is a carboxylic acid and an epoxide.
Preparation
By reaction of acetophenone and the ethyl ester of monochloroacetic acid in the presence of an alkaline condensing agent.
Composition
Strawberry aroma has been the subject of extensive investigation. Several components have been identified, of which only 7% appear to be responsible for the aroma. Strawberry aroma varies widely with the strawberry variety. The most valuable part, aroma, is from wild strawberry.
Aroma threshold values
Detection: 2 ppm
Taste threshold values
Taste characteristics at 1 and 5% sucrose: sweet, ripe, strawberry jam and preserve notes.
Taste threshold values
Taste characteristics at 50 ppm: sweet, berry, strawberry, fruity, tutti-frutti and floral nuances
Trade name
Strawberry pure (Givaudan)
Synthesis
Ethyl 3-methyl-3-phenylglycidate is synthesized by Acetophenone by condensation with Ethyl monochloroacetate in an alkaline solution, using sodium as a condensing agent.
Solubility in organics
Poorly soluble in Propylene glycol, Glycerin and mineral oil, soluble in alcohol, miscible with most perfume and flavor oils.
