Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 355.15 g/mol gives 2,3-dichloro-4-{[6-(4-fluorophenoxy)-3-pyridyl]imino}but-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,3-dichloro-4-{[6-(4-fluorophenoxy)-3-pyridyl]imino}but-2-enoic acid (CAS 219929-79-0) is a high-purity analytical reference standard with the molecular formula C15H9Cl2FN2O3 and a molecular weight of 355.15 g/mol.
The molecular framework of 2,3-dichloro-4-{[6-(4-fluorophenoxy)-3-pyridyl]imino}but-2-enoic acid (C15H9Cl2FN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
