Description
CATO supplies (E)-[2-(4-Fluorophenoxy)-1-(4-methoxyphenyl)ethylidene](methoxy)amine (CAS 338400-75-2), a certified reference material (molecular formula C16H16FNO3, MW 289.30 g/mol) for analytical method development and quality control.
(E)-[2-(4-Fluorophenoxy)-1-(4-methoxyphenyl)ethylidene](methoxy)amine (C16H16FNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), (E)-[2-(4-Fluorophenoxy)-1-(4-methoxyphenyl)ethylidene](methoxy)amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
