Chemical Structure
Description
Ethyl 2-(3-formyltriazylidene)acetate (C5H9N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Ethyl 2-(3-formyltriazylidene)acetate (CAS 69982-16-7), molecular formula C5H9N3O3 and molecular weight 159.14 g/mol, is a CATO reference standard with documented purity and traceability.
