Strawberry aldehyde Usage And Synthesis

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.
Uses	Ethyl 3-methyl-3-phenylglycidate is a synthetic flavoring agent that is a glycidic acid ester. It is a colorless to pale yellow liquid with a strong fruit odor suggestive of strawberries. It is unstable to alkali and moderately stable to weak organic acids. It should be stored in glass, tin, or aluminum containers. It is soluble in fixed oils and in propylene glycol. It is used in flavors for strawberry note and has application in candy, beverages, and ice cream at 6–20 ppm. It is also termed aldehyde c-16.
Uses	Perfumery, flavors.
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
General Description	Clear, colorless to yellowish liquid with a strawberry-like odor.
Air & Water Reactions	Insoluble in water.
Reactivity Profile	Esters, such as Ethyl 3-methyl-3-phenylglycidate, 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.
Fire Hazard	Ethyl 3-methyl-3-phenylglycidate is probably combustible.
Trade name	Strawberry pure (Givaudan)
Safety Profile	Mddly toxic by ingestion. Mutation data reported. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
