(2Z)-2-Amino-3-[(E)-[(6,8-dichloro-4-oxo-4H-chromen-3-yl)methylidene]amino]but-2-enedinitrile (CAS 1024826-43-4), molecular formula C14H6Cl2N4O2 and molecular weight 333.13 g/mol, is a CATO reference standard with documented purity and traceability.
(2Z)-2-Amino-3-[(E)-[(6,8-dichloro-4-oxo-4H-chromen-3-yl)methylidene]amino]but-2-enedinitrile (C14H6Cl2N4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
