2-Cyanoacetamide is an organic compound. It is an acetic amide with a nitrile functional group.
Uses
[edit]Cyanoacetamide is used in spectrofluorimetric methods to determine the activity of antihistamine H1 receptor antagonistic drugs such as ebastine, cetirizine dihydrochloride and fexofenadine hydrochloride.[3]
Preparation
[edit]2-Cyanoacetamide is prepared from chloroacetic acid via Kolbe nitrile synthesis[4] followed by Fischer esterification and ester aminolysis.[5]
