It seems that the ID conversion web server is not working since this Sunday
https://www.metaboanalyst.ca/faces/upload/ConvertView.xhtml
How to reproduce?
Giving the “example” compound names to the query field, and choosing the input type as common names (default) doesn’t return any match.
1,3-Diaminopropane
2-Ketobutyric acid
2-Hydroxybutyric acid
2-Methoxyestrone
(R)-3-Hydroxybutyric acid
Could you check that, please?
