Applicazioni

Cyanoacetamide was used in spectrofluorimetric method for the determination of some antihistaminic H1 receptor antagonist drugs such as ebastine, cetirizine dihydrochloride and fexofenadine hydrochloride. It may be used in fluorometric determination of 3,4-dihydroxyphenylalanine. It was used as post column fluorigenic derivatizing agent for the bio-analysis and pharmacokinetics of chitosan ester in rabbit serum. Cyanoacetamide is the starting reagent for vitamin B6 synthesis. It reacts with reducing carbohydrates in borate buffer to give intense fluorescence andis useful for the automated analysis of carbohydrates as borate complexes.

Note

Store under cool dry place. Ensure good ventilation. Incompatible with oxidizing agents.
