Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(E)-4-((2,5-Dichlorophenyl)amino)-4-oxobut-2-enoic acid (CAS 61832-96-0), molecular formula C10H7Cl2NO3 and molecular weight 260.07 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-4-((2,5-Dichlorophenyl)amino)-4-oxobut-2-enoic acid (C10H7Cl2NO3) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
CATO manufactures (E)-4-((2,5-Dichlorophenyl)amino)-4-oxobut-2-enoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
