Chemical Structure
Description
The occurrence of N-[2-(4-Chlorophenoxy)ethanimidoyl]benzenesulfonohydrazide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-[2-(4-Chlorophenoxy)ethanimidoyl]benzenesulfonohydrazide (CAS 321430-74-4), a certified reference material (molecular formula C14H14ClN3O3S, MW 339.80 g/mol) for analytical method development and quality control.
N-[2-(4-Chlorophenoxy)ethanimidoyl]benzenesulfonohydrazide (C14H14ClN3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), N-[2-(4-Chlorophenoxy)ethanimidoyl]benzenesulfonohydrazide 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.
