ANGELIC ACID Usage And Synthesis

Chemical Properties

White to light yellow crystal-powder

Uses

Flavoring extracts.

Definition

ChEBI: The (Z)-isomer of 2-methylbut-2-enoic acid. It is found in plant species of the family Apiaceae.

Synthesis

Among many methods know n, one uses 2-Hydroxy-2-buty ronitrile to produce Tiglic acid, from which Angelic can be made by Bromine treatment. Another method goes directly from alpha-H ydroxy-alphu-me~h ylbutyric acid which by dehydration yields Angelic acid, or a mixture of Angelic and Tiglic acids.
