Description
CATO manufactures Ethyl (3E)-3-cyano-4-[(4-fluorophenyl)amino]-2-oxobut-3-enoate 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.
CATO supplies Ethyl (3E)-3-cyano-4-[(4-fluorophenyl)amino]-2-oxobut-3-enoate (CAS 1164512-67-7), a certified reference material (molecular formula C13H11FN2O3, MW 262.24 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl (3E)-3-cyano-4-[(4-fluorophenyl)amino]-2-oxobut-3-enoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
