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. |
