Chemical Structure
Description
As a certified reference material (CRM), (E)-[2-(4-Chlorobenzenesulfinyl)-1-(4-chlorophenyl)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.
(E)-[2-(4-Chlorobenzenesulfinyl)-1-(4-chlorophenyl)ethylidene](methoxy)amine (CAS 320422-53-5), molecular formula C15H13Cl2NO2S and molecular weight 342.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (E)-[2-(4-Chlorobenzenesulfinyl)-1-(4-chlorophenyl)ethylidene](methoxy)amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.24 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.
