Chemical Structure
Description
(Z)-2-((4-chlorophenyl)sulfonyl)-N'-hydroxyacetimidamide (CAS 70661-64-2) is a high-purity analytical reference standard with the molecular formula C8H9ClN2O3S and a molecular weight of 248.69 g/mol.
(Z)-2-((4-chlorophenyl)sulfonyl)-N'-hydroxyacetimidamide (C8H9ClN2O3S) 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), (Z)-2-((4-chlorophenyl)sulfonyl)-N'-hydroxyacetimidamide 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.
